Abstract
Aspects of this disclosure relate to compensating for an offset in a receiver. In one embodiment, the receiver comprises a mixer, a feedback amplifier, and an offset correction circuit. The offset correction circuit can generate an indication of an offset in a differential input to the feedback amplifier and apply an offset compensation signal at an offset compensation node. The offset compensation node can be in a signal path of the feedback amplifier. Such offset compensation can reduce or eliminate leakage from a local oscillator at an input port of the mixer and/or at an antenna port of the receiver.
