Abstract:
A Radio Frequency Receiver on a Single Integrated Circuit (“RFSIC”) is described. The RFSIC may include a mixer, a phase-locked loop (“PLL”) in signal communication with the mixer, and an on-chip auto-tuned RF filter in signal communication with both the mixer and PPL, such that the same PLL simultaneously tunes the frequency of the VCO and the frequency response of the auto-tuned RF filter.
