WebAug 10, 2024 · Hi, I would like to make a simulation with 3 voltage controlled switches with Ltspice. Below, the circuit : But, there is a problem. If I put 1V or 0V, like in the picture, in input of the switch there is something in both output. I don't understand why. Any ideas ? Thank you in advance. WebThe metal-oxide semiconductor field-effect transistor (MOSFET) is a semiconductor device controllable by the gate signal (g > 0). The MOSFET device is connected in parallel with an internal diode that turns on when the MOSFET device is reverse biased (Vds < 0) and no gate signal is applied (g=0). The model is simulated by an ideal switch ... tree planting recordWebThe switch model allows an almost ideal switch to be described in ngspice. The switch is not quite ideal, in that the resistance can not change from 0 to infinity, but must always have a finite positive value. By proper selection of the on and off resistances, they can be effectively zero and infinity in comparison to other circuit elements. tree planting report sample

WebThe op amp is designed to detect the difference in voltage applied at the input (the plus (v2) and the minus (v1) terminals, or pins 2 and 3 of the op amp package). The difference is also known as the differential input voltage. The output, then, is the difference sensed at the input multiplied by some value A - the open-loop gain. WebFig. 5.5: LTSpice curve-tracer arrangement for calculating the i - v characteristics of a MOSFET. The i D - v DS characteristic of the MOSFET is obtained by sweeping v DS through a range of voltages while keeping V GS constant at some value. Here the channel-length modulation factor (lambda) is varied from 0 to 0.05 V-1 in 0.01 V-1 increments. ...
