Decoupling and suppression of MOSFET distortion components

If a nonsaturated long-channel MOSFET is driven by linear and parabolic gate signals (α₁V_D+α₂ V_D²) derived from the drain signal V_D , the drain current´s odd and even distortion components are decoupled and can be independently nulled by separately setting the constants α₁ and α₂ under normal bias conditions. The authors present a model which accurately predicts measurements for single-ended and balanced circuit configurations down to at least 80 dB below the amplitude of the fundamental
