Abstract
Disclosed herein are switching or other active FET configurations that implement a segmented main-auxiliary branch design. Such designs include a circuit assembly for performing a switching function that includes a branch including a plurality of main-auxiliary pairs coupled in series, wherein each main-auxiliary pair includes a main field-effect transistor (FET) in parallel with an auxiliary FET. The circuit assembly also includes a gate bias network connected to the main FETs and configured to bias the main FETs in a strong inversion region. The circuit assembly also includes an auxiliary bias network connected to the auxiliary FETs and configured to bias the auxiliary FETs in a weak inversion region.
