LV complementary differential pair with programmable rail-to-rail constant-g/sub m/

Abstract

In this paper a new differential pair architecture with programmable rail-to-rail constant-g/sub m/ is presented. Since the architecture adopts a signal processing method to obtain constant-g/sub m/ it can be implemented in any complementary VLSI technology and it functions regardless of transistor operating regions. An MOS implementation is discussed and is shown to operate in both weak and strong inversion, resulting in a programmable g/sub m/ over a very wide range.
