Abstract
The present invention teaches a variety of transconductance circuits formed having a class AB transconductor amplifier coupled in parallel with at least one concave compensation circuit. When the transconductance circuit has only one concave compensation circuit, the concave compensation circuit is designed with no offset so that the concave transconductance gain of the compensation circuit compensates for the convex transconductance gain of the class AB amplifier thereby providing a more linear transconductance circuit. When the transconductance circuit includes multiple concave compensation circuits, they each are designed with an offset chosen such that the combination of the individual concave transfer functions achieve a more linear transconductance circuit.
