A method and circuit for receiving a radio frequency signal by receiving and amplifying the radio frequency signal to produce a received signal and generating first and second clock signals corresponding to first and second channel signals, respectively, of the received signal and multiplying the received signal with the clock signals to obtain the channel signals. Pre-selectivity filtering of the received signal is performed by filtering the first channel using a first impedance, filtering the second channel using a second impedance, and converting the first and second impedances with respect to one another through a first gyrator. Amplitude limiting of the first and second channels is performed to obtain first and second amplitude limited channels. Poly-phase selectivity filtering of the first and second amplitude limited channels is performed to obtain first and second selectivity filtered channels. The selectivity filtered channels are demodulated to obtain a data signal.
