Abstract :
A dynamic Direct Current (DC)-offset canceller in a receiver of a communication system is presented. The dynamic DC-offset voltage is sampled and then a loop architecture is used to cancel the DC-offset voltage. The simulated results show that the DC-offset voltage is no more than 5 mV after the loop architecture is operated.
