[SOLVED] Design of a differential amplifier

Specifications of a differential amplifier

Hello all,

I am learning from books about two stage differential CMOS amplifiers and I'v designed one of them (see please the figure).

Now I want to find out its :
- SR (slew rate),
- setting time and as well
- ICMR/OCMR (input/output common Mod range),

but I don't know how can I simulate it to get the specifications thinker.

For example: for SR, should be the Vin1 a pulse signal? and what about Vin2..?
or for ICMR, should I tie the input signals VIn1 and Vin2 together and simulate DC?


I would be thankful, if I get some tipps.

Thnaks in advance.

Hi hanover90

Follow this lecture note , at the end you have hspice simulation example to measure characteristic of op ampView attachment Lect2UP250_(100328).pdf
