Abstract
A circuit includes a current source, a differential pair of transistors coupled to the current source, an active load, and a current injection circuit. The differential pair of transistors has a first offset voltage and an input transconductance. The current injection circuit is configured to supply a first current and a second current to produce a second offset voltage across the differential pair of transistors opposite the first offset voltage. The first current and the second current has a same thermal dependence as the input transconductance of the differential pair of transistors.
