Abstract
A circuit for tuning a transconductance amplifier includes a first transconductance amplifier outputting a first current from its output, a second transconductance amplifier outputting a second current from an output that is coupled to the output of the first transconductance amplifier, and a feedback loop. The feedback loop provides a control signal that varies with a difference between the first current and the second current and is used to adjust the transconductance of the second transconductance amplifier.
