Title: "simulator" offset error
Post by alirezad on Nov 30^th, 2008, 6:23pm

I am simulating a perfectly symmetric differential amplifier but I get offset at the output.

It is a gain boosted amplifier. The outputs of the nested booster amplifiers are different by about 1uV and when it gets to the top-level amplifier the offset grows to about 20mV.
I have tried decreasing the simulator tolerances but it doesn't help.

Any help will be appreciated!
