Abstract
A signal processing circuit and method for processing an input signal are described. The circuit includes a frequency selective network, an amplification stage, and at least one continuous-time feedback path from the output of the amplification stage to the frequency selective network. The amplification stage includes a switching amplifier and an analog amplifier. Switching circuitry alternately enables the switching and analog amplifiers for processing of the input signal.
