  • On-off keying receivers
    Patent number: 11502716
    Abstract: An on-off keying (OOK) receiver circuit includes a band-pass filter and an envelope detector. The band-pass filter includes a high-pass filter, a low-pass filter, and a switch. The high-pass filter is configured to filter an OOK input signal. The low-pass filter is configured to filter an output signal of the high-pass filter. The switch is coupled to an output of the high-pass filter, and is configured to, with each cycle of the OOK input signal, dissipate energy stored in the band-pass filter. The envelope detector is configured to receive a filtered OOK input signal from the band-pass filter, and to generate an OOK output signal based on the filtered OOK input signal.
