I want to understand how to find some things out about this particular circuit attached.

I have achieved Vg=3.9Volts

Idss=.5mA

ID=1.6mA

Vgs=2.89Volts

and Av=voltage gain=-2.68

The output impedence i am not sure how to do exactly.

I have calculated these values but PSpice offers a couple different values. Was wondering if anyone got these values or if not how you got them.

Consider the AC-coupled amplifier shown below. All capacitors are 10µF. The

MOSFET has the following parameters: KnW/L = 1E-3 A/V2, Vt = 1 V

2. Calculate the DC-bias point (also called Q-point)

4. Calculate the small-signal gain of the amplifier stage

5. Calculate the input and output impedance of the amplifier in the midband

6. Calculate the small-signal gain of the amplifier with capacitor C3 removed.

Thank you for ANY help!
