APPARATUS FOR COMPENSATION OF ELECTRONIC CIRCUITRY AND ASSOCIATED METHODS

摘要

An apparatus includes a multi-stage amplifier. The multi-stage amplifier includes first, second, and third amplifier circuits coupled in a cascade configuration. The multi-stage amplifier further includes first, second, and third compensation networks. The first compensation network is coupled between the output of the third amplifier circuit and the input of the second amplifier circuit. The second compensation network is coupled between the output of the third amplifier circuit and the input of the third amplifier circuit. The third compensation network is coupled between the output of the second amplifier circuit and the input of the second amplifier circuit.
