Abstract: A transceiver circuit includes a first interface and a second interface that are connected to an optical transceiver device, a receiver circuit, a transmitter circuit, and a compensation circuit. The receiver circuit includes a differential amplifier, where a first phase input terminal of the differential amplifier is coupled to the first interface, and a second phase input terminal of the differential amplifier is coupled to the second interface. The transmitter circuit includes a first transistor, where a terminal of the first transistor is coupled to the second phase input terminal, and another terminal of the first transistor is coupled to a ground terminal. The compensation circuit is configured to provide a leakage path for the first phase input terminal, or provide a compensation current for the second phase input terminal.
