Abstract

A method and an apparatus relating to an amplifier (e.g., an operational transconductance amplifier or OTA) are provided. The OTA includes a first node and a second node. The OTA further includes a differential transistor pair for receiving an input. The differential transistor pair is coupled to the first node and the second node. The OTA includes a pair of output nodes for outputting a response to the input. The response at the pair of output nodes includes a first frequency pole. A capacitive element is coupled between the first node and the second node. The response includes a second frequency pole based on the capacitive element. The second frequency pole is at a greater frequency than the first frequency pole.
