ABSTRACT:
An amplifier circuit for amplifying an input signal received at an input node of the amplifier circuit. The amplifier circuit comprises a feedback resistance connected between the input node of the amplifier circuit and an output node of the amplifier circuit. Transconductance circuitry is arranged to inject a transconductance current at a point along the feedback resistance. The transconductance circuitry is configurable to vary the point along the feedback resistance where the transconductance current is injected.
