ABSTRACT:
A passive wireless receiver to receive an input signal and passively process the input signal to generate an output signal. An embodiment of the receiver includes an input circuit, a dynamic switching circuit, and a switch signal generator. The input circuit is configured to receive an input signal and produce a first output signal. The input circuit includes a passive network configured to condition the input signal. The dynamic switching circuit is configured to perform frequency translation on the first output signal. The switch signal generator is configured to drive the dynamic switching circuit to activate and deactivate the dynamic switching circuit at a sampling frequency that is controlled and stabilized by a frequency control circuit.
