Abstract

A transceiving circuit includes a first transmitting circuit, a first receiving circuit, a first switching circuit and a processing circuit. The first transmitting circuit includes a first inductor and a second inductor, wherein the second inductor is coupled between a first node and a second node, and an end of the first inductor is coupled to the second node. The first receiving circuit is coupled to a third node. The first switching circuit is configured to conduct or block the first node and the third node. When the transceiving circuit is operated in a transmitting mode, the processing circuit is configured to control the first switching circuit to disconnect the first node with the third node. When the transceiving circuit is operated in a receiving mode, the processing circuit is configured to control the first switching circuit to connect the first node with the third node.
