Abstract: A transceiver circuit capable of separating hybrid signal by current is disclosed. The transceiver circuit includes a transmission circuit, a digital/analog converting module for transmitting signals and a receiver circuit for receiving signals. The digital/analog converting module includes an input end for receiving a first digital signal, a first output end coupled to the transmission end for outputting a first current signal, and a second outputting end for outputting a second current signal. The first and the second current signals are generated according to the first digital signal. The first current signal is proportional to the second current signal. The second current signal for generating a replica transmission signal is used in receiver circuit for removing transmit signal from receive signal.
