A radio-frequency (RF) receiver includes a receiver analog circuitry and a receiver
digital circuitry coupled together. The receiver analog circuitry receives an RF
signal. The receiver analog circuitry processes the received RF signal and generates
a digital signal that it provides to the receiver digital circuitry. The receiver
digital circuitry includes a digital down-converter circuitry that mixes the digital
signal provided by a receiver analog circuitry with a digital intermediate frequency
(IF) local oscillator signal to generate a digital down-converted signal. The receiver
digital circuitry also includes a digital filter circuitry that filters the digital
down-converted signal to generate a filtered digital signal. The digital filter
circuitry provides a notch at a frequency that corresponds to a residual DC offset
of the receiver analog circuitry.
