Abstract
Systems, methods, and circuitries are provided for extending the range of an analog-to-digital converter (ADC) associated with interference cancellation. In one example a transceiver includes front end circuitry configured to transmit a radio frequency (RF) transmit signal that includes an intended signal and an interference signal. The transceiver includes self-interference cancellation (SIC) circuitry configured to control the front end circuitry based at least on a digital baseband reference transmit signal that comprises a digital representation of the intended signal. ADC range extension circuitry is provided to: receive the RF transmit signal from the front end circuitry; receive the digital baseband reference transmit signal from the SIC circuitry; approximate the interference signal by generating an analog estimated interference signal that corresponds to a difference between the RF transmit signal and the digital baseband reference transmit signal; and provide the analog estimated interference signal to the ADC.
