Abstract:
A receiver comprises a Low Noise Amplifier (LNA) configured to amplify an input signal and a resonant circuit coupled to the LNA. A first switch couples current from the resonant circuit to a first capacitor integrating a first voltage, wherein the first switch is enabled with a clock signal. A second switch couples current from the resonant circuit to a second capacitor integrating a second voltage, wherein the second switch is enabled with an inverse clock signal. A differential amplifier comprises a positive input for receiving the first voltage and a negative input for receiving the second voltage in order to produce a sum and a difference frequency spectrum between a signal spectrum carried within the current and a frequency of the clock signal.
