Linearity enhancement in the entire tuning range of CMOS OTA using a new tune compensated source degeneration technique

Abstract

This paper presents a tunable linear OTA based on an improved adaptive biasing of degeneration triode-mode transistor and a new technique for compensating the linearity degradation due to the tuning action. Using the adaptive biasing circuit, the degeneration resistance is modulated such that to make constant transconductance in a wide range of input… (More)
