Abstract
An integrated circuit including a circuit for calibration and offset compensation of an amplifier method is disclosed. In one embodiment, the method includes providing a reference input signal to the input of an amplifier, coupling the output signal of the amplifier to a comparator circuit as a first input signal, providing a target signal to the comparator circuit as a second input signal, and increasing or decreasing a control signal provided to amplifier VGA corresponding to the output of the comparator circuit by one adjustment process of small process size.
