cmos differential amplifier
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...
mos differential amplifier
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.

anyone please reply and help me out
What is the value of vthn, vthp, λn, λp, µnCox, µpCox in gpdk 180n library for simulation in cadence spectre.I am using 1.8 voltage supply.
Plz reply if anyone knows.
Its needed to start my ota design.
thanq in advance.

thr is a option finger width.........watz this ??
also in layout in property of mos thr is option threshold...
hey does ne1 hav cadence virtouso help manual regarding how to do various digi n analog analysis lyk delay, power,pdp,min n max vdd,noise ,rms value,capacitance,....................n al that.
plzzzz its urgent!!
