Abstract
An operational transconductance amplifier, that may include a first differential pair that comprises a first transistor and a second transistor that are coupled to each other at a certain node; wherein the first differential pair is configured to convert a differential input voltage to first and second output currents; a current source that is coupled to the certain node and may include an adjustable current sources; and a feedback unit that is coupled to the certain node and is configured to (a) receive the differential input voltage, and maintain a voltage of the certain node substantially fixed regardless of changes in the differential input voltage.
