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