Abstract

A transconductance (gm) control circuit for bipolar or CMOS rail-to-rail input stages is provided. The gm is controlled by the use of multiple input pairs and can be used in CMOS or bipolar technology. In CMOS the gm-control works regardless of the operating region of the MOS transistor, whether it is weak, moderate or strong inversion.
