Abstract

An active hybrid circuit of full duplex channel is disclosed. The active hybrid circuit generates replica voltages in a current output stage to reduce the power at the transmitting end to be transmitted to the receiving end, and especially in high-speed bi-directional transmissions, to eliminate the power at the transmitting end to be transmitted to the receiving end. The active hybrid circuit includes a transmitting digital to analog converter for generating an analog transmitting signal, a receiving analog to digital converter for receiving an analog receiving signal, a replica voltage digital to analog converter for generating a corresponding replica voltage according to the analog transmitting signal generated by the transmitting digital to analog converter, and a plurality of signal mixers for removing the replica voltage from the analog transmitting signal to thus reduce the influence of the analog transmitting signal on the analog receiving signal.
