Classification: CPC H | IPC H

Claim 11:
12. For use in transceiver circuitry in an integrated circuit device, the transceiver circuitry comprising a receive path including an analog front end configured to receive analog signals from an analog transmission path and to condition the analog signals, and an analog-to-digital converter configured to convert the conditioned analog signals into received digital signals for delivery to functional circuitry of the integrated circuit device, and a transmit path including a digital front end configured to accept digital signals from the functional circuitry and to condition the accepted digital signals, and a digital-to-analog converter configured to convert the conditioned digital signals into transmission analog signals for transmission onto the analog transmission path, wherein at least one of (a) the analog front end in the receive path, and (b) the digital front end in the transmit path, introduces distortion during signal conditioning and outputs a distorted conditioned signal in a respective one of the receive path and the transmit path, a method for correcting the respective distorted conditioned signal, the method comprising:
determining, at a respective one of the at least one of the analog front end in the receive path and the digital front end in the transmit path, a respective distortion cancellation function; and
applying the respective distortion cancellation function in one of:
the receive path to cancel a distortion component from the distorted conditioned signal in the receive path prior to the delivery to the functional circuitry of the integrated circuit device, or
the transmit path to cancel a distortion component from the distorted conditioned signal in the transmit path prior to conversion of the conditioned digital signals into the transmission analog signals for transmission onto the analog transmission path.
