Abstract: A transceiver having a shared filter for both transmit and receive modes is disclosed. A transceiver includes a transmitter having an output coupled to a signal node, wherein the transmitter is configured to transmit signals onto the signal node during transceiver operation in a transmit mode. The transceiver also includes a receiver having an input coupled to the signal node, and configured to receive signals from the signal node during operation in the receive mode. The transceiver further includes a first filter coupled to the signal node, wherein the filter is shared by the transmitter and the receiver. The filter is coupled between the transceiver and a first terminal of a transmission line.

Abstract: A power detector circuit that rejects the common mode portion of a differential signal is disclosed. The circuit includes a differential input having first and second input nodes. Differential and common mode circuit paths are coupled to the differential input. The common mode circuit path includes first and second capacitors coupled to respective first terminals of first and second input nodes of the differential input. The second terminal of each of the first and second capacitors is coupled to a gate terminal of a first bias transistor. The common mode circuit path is configured to reject a common mode portion of a differential input signal provided to the differential input such that a differential output signal is indicative of an amount of power of a differential portion of the differential input signal.
