combining diff amp with current mirror if you know DC operation of circuit, then you know a LOT about how the circuit will operate transformers have awesome common mode rejection MIDTERM: current mirrors basic cmos cell differential amplifiers every which way T/F and M/C no miller's theorem project compute open circuit time constant compute gain from miller's theorem can have text book and 1 sheet of paper for equations to be turned in also allowed to have that paper from angel calculator pencil
