Advances in linearised GaAs MESFET circuit design techniques

Discusses the synthesis of linearized conductance functions using GaAs MESFETs which have an approximately square-law drain current versus gate-source voltage characteristic. The functions for realization are derived and implemented in three basic circuit configurations: transconductance, self-conductance, and buffer function. The new circuits outperformed previous circuits in terms of chip area, power consumption, and efficiency. The alternative concept of voltage linearization is introduced. It was used to realize lossless buffer circuits. Optimization of FET gate widths to allow a verified realistic FET model was demonstrated.<<ETX>>
