Abstract :
A new common-mode voltage detector circuit to be used in the common-mode feedback loop of ultra-low voltage fully differential amplifiers is presented. The proposed circuit behaves linearly for most of the signal range and is able to operate with supply voltages as low as 0.4 V. The design issues and simulation results of the circuit in 0.18 m CMOS technology are presented.
