Abstract
A common-mode feedback module is disclosed for controlling feedback in an amplifier, such as a multi-stage amplifier. The common-mode feedback module may include a feedback input stage, a cascode stage, and a feedback output stage. The common-mode feedback module may provide feedback, such as negative feedback to the amplifier to extend a bandwidth of a frequency response and/or increase stability.
