Abstract
A transconductor to convert an input voltage to an output current, includes: a primary transconductance stage to provide the output current from the input voltage and a driving current; an adaptive transconductance stage coupled in series with the primary transconductance stage to generate the driving current from the input voltage; and a bias circuit coupled to provide a primary bias voltage to the primary transconductance stage and an adaptive bias voltage to the adaptive transconductance stage.
