Abstract
An energy-efficient implementation of a WiFi transceiver is proposed in this disclosure. The WiFi transceiver comprises a receive chain comprising a variable receive (Rx) filter circuit and a variable Rx analog-to-digital converter (ADC) circuit. The receive chain is configured to receive a receive signal during a receive mode of operation, having a receive bandwidth associated therewith and receive a transmit signal associated with a transmit chain of the transceiver during a transmit mode of operation, having a transmit bandwidth associated therewith. The WiFi transceiver further comprises a control circuit configured to dynamically adapt a bandwidth of the variable Rx filter and the variable Rx ADC in the receive chain to the receive bandwidth or to the transmit bandwidth, based on the mode of operation.
