I need to design a simple single stage common source amplifier using an N-type enhancement mosfet (2N7000).
The gain Av should be 100.
With sufficiently large drain resistance -- which implies either a high supply voltage (s. image below) or respectively low drain current you can achieve such Av : [ATTACH=C

usually in power amplifier design u need to use LSSP , which is based on HB simulation , small signal S parameters are not ususally used in PA
also it will be not vaild at all if u design a class C PA
so use HB , or LSSP

The simulator does provide a right leg terminal so why don't you use it? In any case an instrumentation amplifier needs some means to enforce a common mode voltage in the specified range. If you don't use a RL circuit, you must have Mohm bias resistors to ground at the inputs.

Dude, your schematic looks like shit. Its very difficult to understand it.
The PMOS transistors will show Id as negative that is a convention and does not mean that something is wrong.
How have you designed this amplifier?
How are you generating the bias voltage for the gate of M1 and M2?

You will need to know and work out the biasing for the transistor eg. the collector resistor value and what is the power supply voltage you will be using, also you will need to bias the base as well. Not to mention working out the value of the decoupling capacitor at the emitter, based on the lowest cutoff frequency you would like for your amp
