中文摘要	A novel low-power DC offset calibration(DCOC) method independent of intermediate frequency(IF) gain for zero-IF receiver applications has been reported. The conventional analog DCOC method consumes greater power and affects the performance of the receiver. The conventional mixed-signal method requires enhanced memory to store the calibration results at different receiver gains as the DC offset is relative to the radio frequency(RF) and IF gain. A novel algorithm is presented to make the DCOC process independent of IF gain, which significantly reduces the memory area. With the proposed circuit, the receiver calibrates only once so settle-time and power consumption of the IF circuit is lowered. A DCOC circuit with the proposed method is manufactured in 0.18 μm CMOS technology that drains nearly 0 mA equivalent current from a 1.8 V power supply.; A novel low-power DC offset calibration(DCOC) method independent of intermediate frequency(IF) gain for zero-IF receiver applications has been reported.
