ABSTRACT:
An amplifier including a current source transistor for supplying a current to a node from a voltage rail and an input transistor switching the current at the node in response to an input signal chopped by a chopping signal. A cascode-chopping transistor operating both as a cascode transistor and a chopping transistor couples the node and an amplifier output in response to a bias voltage chopped by the chopping signal.
