For the circuit in problem 3, simulate the circuit using PSPICE. For the BJTs use parameters: IS = 1E-15, BF = 50. Apply a 0.01 volt peak 1KHz sine wave and plot the output voltage. Confirm that the device q points and the voltage gain of the circuit match your calculations. Turn in the schematic, the portion of the output file showing the q point, and a plot of the output. Use 1 µ F capacitors....
