Good afternoon. I am attending a course in electronics in Portugal, and I'm having some doubts in the design of a two-stage amplifier in CMOS technology.
I cannot get a sufficiently high gain, about 100000V / V.
And the unity gain frequency should be about 1MHz.
The input stage is a differential pair with PMOS and the output stage is a common source.
I would appreciate some kind of help.
I enclose pictures of my circuit and the corresponding Bode diagram.
Thank you for your help and sorry for my English.
