ac analysis of differential amplifier
Hi,
Can any give me a article about the simulatin of diferentialal op. amplifiers. The circuit is a two stage amplifier: the first stage is telescopic amplifier with PMOS
input transistors, the second stages are inverters with activ load (PMOS tranzistor).
I tryed to make AC simulation but the output voltages of the inverters went to VDD.
There is a cooommon mode feedback circuit but obviously it doesn't work properly.
