Original Abstract

This problem is solved by topology which uses two amplifiers. The first of them (auxiliary amplifier) works in two phases. During the first phase it compensates its own input offset while during the second phase it continuously measures and controls offset of the main opamp. There exists more techniques allowing the continuous offset compensation of the main (or both) opamps by extra input. The presented solution was designed and manufactured in CMOS07 technology and allows designer to simply use even already designed Miller-OTA opamps with minimal adaption.
