As far as I've correctly understood, before the U13 you have a circuitry that inverts the slope of the signal, that means increasing the input voltage, the input to U13 decreases. Furthermore this circuitry, toghether with U13 add an offset voltage. If this is correct then the signal at the iput of the opamp is: Voa = -k*Vin+b Where "-k" is t
Hi, I made a research about WPE and I have seen that below some distance there is not any difference between PMOS and NMOS devices, i.e. in both cases the voltage threshold increases. But I am not sure if this conclusion is correct or if there are another properties that can be different due to its mobility carriers variation, stress/strain e
Hello Everyone, I am really new at PCB design and forum. Maybe my questions would be silly if so, sorry in advance :) 159655 The PCB at the top is my design for BLDC motor control. The bottom one is a commercial product. well, as you can see there are some differences I want to ask about them. [ATTACH=CO
here is a photo of it. i think the magnet is glued on top of the ferrite core. If it is an s-correction part, is there any use of it in the amateur radio world? what are the properties of the choke then, i mean can it be used as a saturable reactor permanently saturated in just one cycle of the AC applied to it? like an imperfect diode for AC.
The message is just a warning about the simulation, it doesn't mean there is a problem with the code. The OSCCAL register applies a small offset to the internal oscillator calibration but the exact amount it shift the frequency is not well defined. The main calibration is done in the factory with the OSCCAL being left to the user for 'fine tuning'
Hi, Do you mean an internal signal? Or a signal on a pin? Which pin? (Use the number or the name as in the datasheet.) Klaus
Hi, On page 8 of the BCM4414xD1E5135yzz DCDC module datasheet, it says that the Input overvoltage threshold is 420VDC?..and then the recovery from this happens when vin falls to 405VDC. Does this mean that the module resumes into full operation as soon as its vin falls to 405v, or is there some additional time delay added aswell?eg the 290m
Hi Akanimo, Not sure what you mean by switching and averaging. Component values are all in schematic, awol L2 is also 100uH. It was just messing around, as two people have pointed out contras to doing that with a SEPIC, I'll leave that experiment there but curious as to what you think could be done with it.
you gave certain voltage readings as: 8V - 0,70V 10V - 1,95V 12V - 2,83V... what does it mean ? you may have to explain more on the damaged meter and how did you took the readings. whether the meter is working or the component connected to it is damaged. a simple handdrawn circuit of the meter with preferably a photo will help.
I'm trying to create a univibe tyoe of guitar effect. That will consist of a timebase i.c. that will vary the sound to create a tremelo effect and various other phasing sounds. (Variable speed 1 to 30Hz) The trouble is I can't get it past the breadboard, although it works well enough I cannot avoid the sound of the I.C. switching, whether it be
EMC compliance must be achieved for the final product with typical application wiring (power supply, signal and communication cables). I don't understand what you mean by "have to define dB levels for both"?. Conducted emissions are measured at the external power supply lines, possibly also other external cables. Question is which modules are ex
Ok thanks. Do you know if there is any way that i can only use 6 of my 10 ports? I'm not sure what you mean by this. Are you wanting to visualize the fields when you've excited six of the ports? In this case, just set the power magnitudes at these ports to a nonzero value, and reload the field plots. The power repre
Was there ever produced a mini LCD TV with SCART input? The smallest I have found is 14" and this is CRT.
I would place resistors 1-4 very close to the left pad of At1.1. Use 50 Ohm track from SMA connector to resistors 1-4. Place one pad of resistors 1-4 on the 50 Ohm track. Since your substrate is rather thick, the main parasitic effect is series inductance. Place the resistor pad on the main track will reduce the parasitic ind
12v 1A.... You mean this kind of thing? - - - Updated - - - In the UK, we have a company called stontronics who order the kind of thing you want from china. Because they have a cl
Stupid question, maybe: Why mess around with the sensor side of things, why don't you just modify the output circuit to be controlled by the switch? And what do you mean 'it transmits a 1'? Is it a serial stream, or do you mean it goes high? And, what do you mean "It is OK to generate more than one digital signal "1"? As Brian says, show us (...)
Hi, well I think you are over-thinking it. Take a look at AN 4151 by fairchild The basic point about an LLC is that when you are switching at the upper resonant frequency , then the converter simply operates like an ideal transformer, and Vout/Vin = if the load is anything from 20% 10 100%, then Vout/Vin = Ns/N
If I write 1 << (twint) on an arduino ide, does that set or clear the twi interrupt flag of the twi control register? I tried researching on the internet, I cannot find an answer.
Sad but true. Summary: do not worry but be careful. Thanks! I wonder many people in the past decades were in front of CRT screens, I mean close to them (thinking of the computer people). If significant X-ray radiation was escaping by them, we would be all dead. Many ignored this fact completely. I have seen people e
Hello everyone. Recently my chief has given me task to think about receiving part of our prospective system and additionally told that i should search for LNA with the lowest possible noise. Unfortunatelly im not RF circuits engineer, but nonetheless i have read necessary chapters from popular books like Microwave engineering by Pozar, and nowaday
