1. ### Comp Sci PSPice Lab Exercise - Differentiator (Circuit)

Look, this is a weird one, but I really need help. This is the Electronics Laboratory, that is supposed to be hands-on, but with Corona it got cancelled. However, they announced that we'd do it through the internet, had us download PSPice, and now we basically have to try and "translate" the...
2. ### Engineering Measuring the damping frequency from an oscilloscope reading

I know the following equations for if the damping ratio is less than 1: $$\sigma = -\zeta \omega_n$$ $$\omega = \sqrt{(1 - \zeta ^2)\omega^2_n}$$ I am given the following circuit that I built on LTSpice: Measuring the voltage between node 2 and ground (blue), and the voltage Vc4(t) (green) I...
3. ### Error message in PSpice

Homework Statement Run a transient simulation and plot the three outputs, Vo(t), on the same plot. Use the following settings: 1. Set the Run Time (or Stop Time) so that you plot 3 cycles of Vo(t). 2. Set the Maximum Step Size so that you get at least 100 points per period for Vo(t). 3. Set...

5. ### Problem with Pspice simulation

Hi, I have a strange problem with Pspice, it always shows after successful attempts, the simulation program stops working and all voltages markers turns to gray and cant see any results any more
6. ### Simulation aborted because there are errors during netlisting

I have built the following circuit: http://i1226.photobucket.com/albums/ee410/jean28x/pspicemodel.jpg However, when I try to simulate it, I get an error that says "Simulation aborted because there are errors during netlisting. Please refer to the sessions log." What am I doing wrong? I'm new...
7. ### Pspice ring oscillator

Homework Statement I'm required to design a simple ring oscillator... One with three stages of cascaded cmos inverters using pspice capture(student version) Homework Equations The Attempt at a Solution I have simulated the circuit with a 5v supply but all i see is a dc line at 2.50v.has...
