Abstract:
Apparatus and methods are provided for calibrating and operating a receiver circuit. An exemplary method comprises the steps of applying a first voltage offset to a first input of an amplifier circuit, generating an output signal at an output of the amplifier circuit based on the first voltage offset and a second voltage offset at a second input of the amplifier circuit, adjusting the second voltage offset based on the output signal, and maintaining the second voltage offset at a constant voltage when the output signal is indicative of the second voltage offset cancelling the first voltage offset.
