Abstract: An apparatus includes a first control circuit having an output and including a first comparator and a second control circuit coupled to the output of the first control circuit. The second control circuit includes a second comparator configured to: compare a first value to a reference frequency value, the first value indicating a frequency of a signal at the output of the first control circuit; and provide an adjustment value to change a hysteresis window of the first comparator.

Abstract: A bidirectional capacitive isolator includes a capacitive isolation network, a first transceiver circuit, and a second transceiver circuit. The capacitive isolation network includes a first port and a second port. The first transceiver circuit is coupled to the first port of the capacitive isolation network, and includes circuitry configured to cancel signal transmitted by the first transceiver circuit from signal received by the first transceiver circuit. The second transceiver circuit is coupled to the second port of the capacitive isolation network, and includes circuitry configured to cancel signal transmitted by the second transceiver circuit from signal received by the second transceiver circuit.
