Abstract: In an example, a CAN transceiver includes a first transistor having a control terminal, having a drain coupled to a voltage supply terminal, and having a source. The CAN transceiver includes a second transistor having a drain coupled to a control terminal of the first transistor, a source coupled to the source of the first transistor, and a control terminal. The CAN transceiver includes a bias circuit coupled to the control terminal of the second transistor, the second transistor configured to convert the first transistor to a diode configuration responsive to detecting high voltage noise.

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.
