Abstract:
1. An amplifier for processing a differential input received at a differential input port, the differential input including a first input signal and a second input signal, the amplifier comprising: a first amplifier circuit, disposed in a first signal path between a first input node of the differential input port and a first output node of the amplifier, the first amplifier circuit arranged to amplify the first input signal received at the first input node and accordingly generate a first amplified signal to the first output node; and a second amplifier circuit, disposed in a second signal path between a second input node of the differential input port and a second output node of the amplifier, the second amplifier circuit arranged to amplify the second input signal received at the second input node and accordingly generate a second amplified signal to the second output node; wherein a driving capability of the first amplifier circuit is different from a driving capability of the second amplifier circuit, and a loop gain response of the first amplifier circuit is substantially identical to a loop gain response of the second amplifier circuit.
