Abstract
This paper presents a modification of the standard autozero (AZ) amplifier topology that requires less chip area for achieving high offset performances. To improve the charge injection effects on the residual offset voltage a high gain ratio between the signal path and offset compensation loop is implemented. The novelty of this design consists in the different two input pair topologies used.
