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 2.4GHz, 2.3GHz and 100MHz, respectively. The measurement results of the proposed mixer exhibit 6.7dB of conversion gain, -18dBm of P-1dB compression point and -7.5dBm of IIP3 with -8dBm LO power and 1.8V supply voltage. The power consumption in mixer core is 5.94mW. This mixer was fabricated in 0.35um 1P4M CMOS process and the size is 1.5 × 1.1 mm2. It can provide 0.7dB conversion gain even though 1.3V supply voltage is utilized.
