MOSFET drain current second-order nonlinearity has a significant impact on the linearity of current regulated CMOS active inductors. It tends to compress MOSFET transconductance $(gm) by generating excess dc current (IEX) in the channel, which is a function of incoming input signal amplitude. This g...
