Abstract :
Based on traditional Gilbert Cell prototype, a 5.8 GHz down-conversion mixer which conclude CMOS gm Cell and LC tank is demonstrated in this paper. The RF, LO and IF port frequencies are 5.8 GHz, 5.75 GHz and 50 MHz, respectively. With SMIC 0.18 um process, simulation results show 3.2dB of conversion gain,-0.8dBm of P-1dB compression point and 7.9 dBm of IIP3 with -5dBm LO power and 1.2 V supply voltage.
