mos differential amplifier

hi
I want to do DC analysis for mos differential amplifier in differential mode and in common mode .
Please tell how to give input signals for both cases in cadence virtouso.
thanx

I don´t understand your question.
If you want something specific to do (in this case a dc analysis), you certainly know what you like to get ? Voltages, currents or something else ? As a function of what ?
Temperature ? No, certainly not. Most probably, as a function of input signals.
Differential or single ended or common mode ? You have the choice !!
But how can we know what you want to do ?

cmos differential amplifier

hii
thanx for your reply
i want to plot gm Vs Vin and differential output voltage Vs diff input voltage.
I hav used a simple pmos current source load and diff pair are of nmos...so it converts diff input signal to single ended output signal.
I am not able to make test bench for diff made, common mode analysis...I am a newbee to analog circuit deisgn
Please help me
