I use HFSS to simulate a bandpass filter with WIDE gaps between its coupled lines. These wide gaps made the simulation time very long and hard to converge. In fact, very small meshes are required to correctly solve the problem. Is it any trick to manage this problem? I heard about spare lines in gaps (these spare lines should be assigned vacu
or there is another way to do it? An immediate workaround to reduce the oven temperature deviation could be achieved by splitting the heating ellement into 2 parts or more, controlling them independently. This way you would be able to quickly rise the temperature at the beggining of the process heating both, but
i have managed to come so far, am I going in right direction ? Right - so far. I see that you already reduced the via size which is reasonable and helpful to fit the routing. A possible problem can be seen in the initial post's screenshot, cutting the ground plane with too small residual connections.
Edit: Ok. Here you go. I am attaching the mikroC PRO PIC project I made. You can't reduce the delays more. It took just 15 minutes to write this code.
Hi everybody, I need a circuit that avoid crow bar current at the driver 125738 Please suggest me circuit that can do such a thing, and it produce smallest propagation delay. Thanks
Hi Can someone explain how IR drop increases with scaling? Also, since the volatge is scaled, shouldnt the current reduce?
To reduce crosstalk track space to width ratio 3x is suggested here, but this assumes a ground plane. 50 ohm tracks are approx equal to dielectric thickness and approx. match CMOS driver impedance on most but not all LV logic.
The battery datasheet shows a load current of 100uA makes its life only 10,000 hours. You must reduce the load current to only 50uA for a battery life of 20,000 hours. If you cannot reduce the current then the battery is too small.
Hi, How can we identify 2(or more) power gated domains have same power characteristic? This is to reduce the number of power gated domain in a partition. Please help me out here. Thank you
Red LEDs are the ones which brings the smallest drop voltages, being perhaps the suited color. Although alkaline batteries exhibit a smooth discharge profile over time, it sounds not a good idea to use a LED too close of the minimal drop voltage due to the fact that the smallest change in its characteristic would dramatically reduce the its bri
The problem with a diode may be an overvoltage condition with very low load, as well as significantly larger drop (loss of regulation) on maximum load. The really elegant solution would be to use a low-dropout regulator ("LDO") to reduce the voltage from 5v to 4.2V. However, the "5V" is not always 5V, as tehre will be some load-dependent drop in
Have you checked resistive directional couplers? There is an example at However, its insertion loss is high. Hence, you should reduce the coupling below 30 dB..
Dear Members I have already designed and fabricated a 3D conical antenna working at GSM frequency bands (Height = 15 cm). Now in order to reduce the size of the antenna (Height cm in particular), I need to design or shape the cone in the form of Waves (sinusiod or meander in 3D). I would like to know how can I achieve this wavy structure
I can only answer it at a very top- (concept-) level. In order to reduce the negative slack, try to reduce the combinational logic between two the two registers (flip-flops). Or adding a pipeline can also be a solution. If your design is big, try out 'incremental compilation' to achieve timing closure for a particular partition that does not
I have doubt will something like this work? Can MCU AT89S51 source current approx 20mA to drive the displays? In fact, a resistor of 560R would limit the maximum current for something near to 8mA. I suspect that the intrinsic 51's inner pullup resistors would also reduce the current a few more. You could add some
reduce supply voltage to min and test for margin at speed with your design. Avoid metastable or race conditions use synch clock for critical timing. Poor design choices can obviously reduce speed integrity issues. Raising voltage 5~10% can make marginal designs sometimes room temp or colder.
"Reverse short channel effect" is now a thing. Used to be that VT would reduce w/ L due to short channel effects, drain field summing w/ gate field. But modern technolgies are not much like what you are shown in school for a classical MOSFET - multiple implants (halo, LDD) and these are tuned for the bleeding edge leaving the long channel "analo
1) Use resistors as a voltage divider to reduce the 500V to 100 V down to 10V to 20V. 2) Use an opamp to add an offset voltage of -10V to the voltages divided then the 10V becomes 0V and the 20V becomes 10V.
This is basically an auto-transformer with 2 relays to choose 3 input taps and 1 relay to select either of 2 taps to give - 6 combinations of voltage ratios , - 4 combinations to boost, - 1 combo to reduce line voltage - 1 combo on 1:1 (240V tap) - 1 relay just enables the output you figure out the
Hi everyone, I am a super novice at this stuff, but I have made a "sound system". A speaker unit with 3 channels, which can listen to the 3 channels simoutanously or by demand. On the microphone unit you can setup the channels. I want to reduce the "background" noise / noise from the amplifier. There are way too much noise, when all 3 channel
Hello all, I working on project that ons the relay when 3 phases are on and offs the relay when 1 or 2 or all 3 phases are faulty. I need direct 3 phase connectins to pic 16f628 no tarnsformers , optocouplers etc. I attached one image that tells when 3 phases are available then what happens. See image bellow124689 Can i u
I think this option has more potential if you reduce the coupling capacitors and apply more damping. - - - Updated - - - Measurements on a breadboard test circuit also look promising. Trace one is the primary drive signal and lower trace measured on the gate of main FET.
Hello, I'm quite new to the subject of these tubes. I've made some basic models but when it gets to the point of creating a port I see that reflections from the input port seem excess to me. For example an incident amplitude of 1 in port signals view has a value of 0.4 for O1,1 which I guess is pretty much. I've tried changing port sizes, of c
How to reduce the height of a monopole antenna without using any lumped elements??
SDA and SCL waveforms look like you have too high pull-up resistor values. To allow checking of signal timing, you should capture SDA and SCL with two oscilloscope channels. You should also reduce the image size of the screenshots before posting.
hi, 1) reduce total design mesh density. you can reduce in steps until simulator successfully complete the simulation. 2) reduce mesh density of particular section of the design. if you feel particular piece of the conductor not significantly affecting the design parameters, you can reduce the mesh density in that area. 3) (...)
In case of doubt, a H-bridge is the straightforward way to implement a peltier power supply. It's presumed that you have sufficient L or LC filtering to reduce the peltier current ripple to a level where it doesn't cause significant efficiency loss. Nonlinear peltier characteristic is a point to consider. It can be either compensated in the cont
Hello, I need add to my design DAC and Voltage Ref. unfortunately, the price limit says it has no money and and therefore I have to use low cost components. As Vref any as TL431. Unfortunately, slightly larger temperature drift and noise than I imagined. Temperature drift is problem, bud partly it to me hopefully compensate by software. Questi
To fix the setup violation, one need to reduce the data path delay. So as you only suggested that it could be done through either up-sizing the cell or adding the buffer. Adding the buffer will need extra space as well as routing resources where as up-sizing the buffer will have advantage in terms of area. Adding the buffer will ONLY help if the t
As all inductive loads, the motor causes contact arcing. You can reduce, but not completely avoid it by placing an RC snubber across the relay contact, e.g. 47 ohm + 100 nF. The capacitor must be rated for 250 VAC.

Equipment having heatsink designs based on passive heat conduction have their performance strongly enhanced by external forced ventilation. There are available on hot regions of the world cheap cooling stands designed with 2 fans which blows a continuous air flowing upwardly, and are able to reduce a bit the overall temperature. The only issue is w
The difference between TC and TC_int is that a 1'bz state in TC will get converted to 1'bx. It would make a difference if these signals were used in a casez() statement, but only if they could have been assigned the 1'bz value. The comparator is written this way to reduce X pessimism by doing the comparison bit by bit. The === operator is only dif
hello have you got a galvanic insulation for your AC signal ? Any link with the MAin AC power ( ground, earth,neutral) Maybe your AOP can oscille at H.F., because high speep AOP. you can reduce the Frequency band width C accross feeback
The cap value should not be so small that its charge loses more than a few percent during the idle half of the cycle. However if you need to reduce output voltage, it is possible to do this by reducing cap values. A gang of small capacitors in parallel, may be better than one large capacitor, to carry large Ampere burdens.
reduce the 1k resistor to around 270 Ohm. That should give you near the 20mA you need through the LEDs for full brightness.
hi thanks for that. what is the limitation on number of metal tracks? why cant we reduce less than 7 tracks? how do we fix them this many number of tracks should be there? i mean supporting calculation of tracks and their widths.
Dear Neo, Capacitive loads often give rise to problems, in part because they can reduce the output bandwidth and slew rate, but mainly because the phase lag they produce in the op amp’s feedback loop can cause instability. Although some capacitive loading is inevitable, amplifiers are often subjected to sufficient capacitive loading to cause
The zener diodes produce distortion and the simple two RC filters will not reduce the distortion much.
Two Options are there. 1. reduce the Higher layer metal area, which means change it to different track. 2. Add the reverse-bias diode at the gate.
Consider that these "intelligent switches" are performing slow switching to reduce EMI, so pwm frequencies should be moderate, e.g. a few 100 Hz up to 1 kHz. And there should be a freewheeling means for inductive loads.
hi Nano_o, its weird problem you facing. what is the frequency step size you using for ADS simulation? reduce the step size to get more data points so the results will match your CST.

The rated Phase Margin is ΦM=60 Degrees @ CL = 20 pF for 220pF the graph shows 40 deg PM YOu have RC 16k5 and 2.2uF which probably reduces the PM near 0. COnsider 1st Opamp with non-inverting gain of ~4 and eliminate 2nd Op AMp to improve phase margin then reduce C8 and double R9 The reason is the CMOS output Z is 5V/7mA (shorted cct) = 0.7
hello there. I am working on ADC SAR, and focus on ENOB, therefore how to increase ENOB and reduce Power consumption.123033
If you plan 50 Hz frequency, then a 4H primary inductance is reasonable. That is the default value when I place a power transformer in the simulator (Falstad's). However as post #2 states, you can make the frequency faster, allowing you to reduce certain parameters for the transformer. [
Hi guys, I know its to much , Im looking for a schematic design about 12v fan that can automaticaly reduce its speed in a minute interval . From 100% to 60% to 30% until zero. Thanks sir,
I bet no one tells you of the distortion of the CT output due to the magnetising current It´s not too rare to see many CT somewhat oversized to the power consumed by the load resistence. Should we assume that it is done to reduce the effect of the remansescent magnetism ?
Hi, I am designing a wireless audio generator which has a sam s70 device (running at 300 Mhz from an external 12 MHz crystal), a CS42L51 audio codec, a ATWINC1500-MR210PB, audio jack connector, usb connector, Leds and switches. The interfaces will be: SPI for the wifi module, I2C for the audio codec, I2S for the audio Codec (including a 12 MHz
i cant understand.Neither we can't understand your problem because you didn't give any useful information about your antenna design. But you could try to reduce all antenna dimensions by 10 percent....
pouring power planes is just about making current loops narrower in area, and thUs less radiative, and less susceptible to pick up interfering better for EMC. IT MAY ALSO reduce I^2R losses. (sorry about caps)
