A CMOS Low Voltage High Linear Down Conversion Mixer Design

Based on traditional Gilbert Cell prototype, a 900 MHz down-conversion mixer which conclude class AB transconductor and LC tank is demonstrated in this paper. The RF, LO and IF port frequencies are 900 MHz, 800 MHz and 100 MHz, respectively. With SMIC 0.18 um process, simulation results show -1.2 dB...

Description
Summary:Based on traditional Gilbert Cell prototype, a 900 MHz down-conversion mixer which conclude class AB transconductor and LC tank is demonstrated in this paper. The RF, LO and IF port frequencies are 900 MHz, 800 MHz and 100 MHz, respectively. With SMIC 0.18 um process, simulation results show -1.2 dBm of P-ldB compression point and 8.5 dBm of IIP3 with -5 dBm LO power and 1.2 V supply voltage.
