摘要	This paper presents a 5GHz double-balanced mixer with DC-offset cancellation circuit for direct-conversion receiver compliant with IEEE 802.11a wireless LAN standard. The analog feedback loop is used, to eliminate the DC-offset at the output of the double-balanced mixer. The test results show that the mixer with DC-offset cancellation circuit has voltage conversion gain of 9.5dB at 5.15GHz, noise figure of 13.5dB, IIP3 of 7.6 dBm, 1.73mV DC-offset voltage and 67mW power with 3.3-V power supply. The DC-offset cancellation circuit has less than 0.1mm(2) additional area and 0.3mW added power dissipation. The direct conversion WLAN receiver has been implemented in a 0.35 mu m SiGe BiCMOS technology.
