Abstract

A CMOS down-conversion mixer with the combination of Gilbert Cell mixer and modified low voltage design technique using LC-tank is demonstrated in this paper. The RF, LO and IF port frequencies are 2.4 GHz, 2.3 GHz and 100 MHz respectively. The measurement results of the proposed mixer exhibit 6.7 dB of conversion gain, -18 dBm of P/sub -1 dB/ compression point and -7.5 dBm of IIP3 with -8 dBm LO power and 1.8 V supply voltage. The power consumption in mixer core is 5.94 mW. This mixer was fabricated in 0.35 um 1P4M CMOS process and the size is 1.5/spl times/1.1 mm/sup 2/. It can provide 0.7 dB conversion gain even though 1.3 V supply voltage is utilized.
