    Design a bias network using Cadence Spectre (or other CAD software as longs as I can easily follow your steps). Must generate a 10uA current with gm = 100uS that cannot vary by more than +-10% over -40 C to 130 C or supply variations of +-10% with a nominal 1.8V supply. You come up with the idea of using a constant gm bias circuit to bias the amplifier. Design the bias network and determine the d...
