Hi:

What relationship is there between Ibias and Icq and Ieq in a Class AB
Complementary-Symmetry Amplifier? I am trying to put together a design
procedure. I assumed that you would choose the Ieq first and after that
I am not sure. I have tried various scenarios using LT Spice. Some worked
and some did not. Also, is there a difference in the design process
between small and large signal? What criteria would one use to
differentiate between small and large signal?
