ABSTRACT:
This document discloses, among other things, a front end circuit having a selectable center frequency. The center frequency is selected based on a control signal proportional to a phase difference between a reference frequency and an amplifier output. A resonant frequency of a tank circuit coupled to the amplifier is tuned using the control signal.
