Abstract
The present invention relates to a radio receiver adapted for use in a time division multiple access (TDMA) system. The radio receiver includes DC compensator circuits configured to decrease the time required to cancel DC offset before received data bursts by DC coupling a radio frequency (RF) demodulator to a baseband channel. The radio receiver may also employ AC capacitive coupling having time modification so as to increase the AC coupled setting time and provide a low pole in a RF-to-Baseband interface.
