Hi all, What is the best floorplan of a LC-VCO 12GHZ in terms of minimizing the parasitic inductance of the connection tracks? Should I connect the GM active (-R) circuit just after the inductor legs or just after the capacitor bank ? reminder: Connection tracks = the 2 main top level wide metal tracks on which inductor, capacitor bank (...)
can you tell any other simulator, i am using ltspice, or any online circuit simulator - - - Updated - - - i am getting 0-600mv when only one of the source is being used, i tried using online simulator, they are giving 0 voltage, when both the sources are active You do not
The standard microcontroller's active low reset circuitry comprises not only a pull-up resistor, but also a capacitor and a diode which respectively provide the ability to filter possible glitches on the power bus (such as due to hot plugging the board to the power connector), but also allow the fast reset to avoid unespected behavior of the progra
Underlying topography makes the bottom plate nonuniform (not-flat) and this can affect the dielectric's uniformity, its local breakdown and reliability and perhaps a bit of mismatch as well. If the foundry didn't characterize and qualify the effects of topography-under-capacitor, they will likely not allow it. Not just the active area but the
It appears that one side of the varactor bias is used to bias the active gain device which avoids capacitor blocks thus avoiding additional parasitics.
Accumulation, if it's used / implemented properly, can be a better cap area than inversion. But if you want to use a standard MOS, your bottom plate contact is not the S/D but the body tie (tap) which in many kits is left as almost an afterthought, placed as sparsely as the rules allow. If you made a "depletion MOS" (like, N+ active in Nwell) then
This of course simplifies to a plain old biquad, and we can tap at different points in the loop to pick different zeros to get HP (first order zero), BP (second order zeros) or LP response (no zeros). I've look at 3 different structures and they all work the same way. The insight I'm still lacking is a clear mental picture
The feedback factor is larger than unity if it is not a PASSIVE but an active feedback path (with another amplifying unit). Example: Phase-lead integrator. In this circuit the feedback path consists of an inverting opamp amplifier in series with the integrating capacitor - fed back to the non-inv. opamp termnal. Advantages: The parasitic phase shif
Hi for all with fuzzy controller type 1 i want to regulate the capacitor voltage of un active power filter to make it fixe as well with reference and other side having THD<5% ,i used an inverter NPC 3 level . problem: when i regulate voltage to 600V i can't save the THD<5% then when i saved it i can't regulate the Vdc with reference for th
Hi, I would like to retrieve pulses out of the mains plug, using only passive components and diodes (no active devices). A reverse sawtooth, or alternatively a capacitor discharge pulse curve is desired, not square pulses. If capacitor discharge is used, the sharper the charge dime and the longer the discharge time the better. Could you (...)
Passive or active? Impedance? Voltage? Linear or Switched capacitor blocks or Digital with filter libraries?
You made a mistake in your Zout calculation. In this circuit Ib is not equal to 0A. To find Zout we "short" transistor base terminal to ground. But this "short" is only for AC signal. And this means the in real life we "short" transistor base to GND via large capacitor. So transistor is ON and still work in active region. obrazki.
The Source sells cell phones. Guess who owns them now? Bell Canada of course. There was active Electronics but most or all their stores are closed now. Sayal Surplus Electronics has two big stores in Missiassauga.
This circuit is an undervoltage protection that keeps the capacitor C62, C46, C69, C67 as charged. This is an active protection and works when output voltage goes below some milivolts i dont know whether it can be adjusted. In case of undervoltage situation, these capacitors add their voltages onto the output voltage so that output voltage r
Hello, The active clamp forward can certainly be arranged to have zero switch_on switching loss (by suitable sizing of the leakage inductance). Since at switch off, much of the FET drain current is diverted into the clamp capacitor, (ie rather than it going through the drain_source of the FET) can we also say that the switch_off switching loss
I build a small mixer circuit from, Electronic Projects for Video Enthusiasts, and i want to plug its output into a Nokia 1200 mobile phone. If I connect the mixer output to a bench amp it works very well, but if i connect it to the headset mic, it is very soft. Any ideas, please.
I want to know how the capacitor can be used as a inductor Together with an operational amplifier a capacitor can mimic a lossy inductor - and if you can afford to apply two opamps (GIC configuration) you can simulate a nearly ideal active inductor.
Dear all .. what is the procedure of simulation of microstrip antenna along with the components like resistor, capacitor, varactor and pin diode in IE3D or CST MWS. Can you please send the link for such documents. Thanks
What are you utilizing to power the device? A poorly regulated power supply combined with the Brown-Out Reset (BOR) active can cause the device to repeatedly reset, essentially suspending device operation. I would recommend utilizing a 100nF decoupling capacitor as close as possible between the Vdd and Vss pins, use a well regulated power supply
Hi, someone knows this kind of filter? 92920 I've calculated transfer function with sapwin but now i want to obtain the center frequency of bandpass. Anyone could help me?
