Based on traditional Gilbert Cell prototype, a low voltage and low power down-conversion mixer which conclude class AB transconductor is demonstrated in this paper. The RF, LO and IF port frequencies are 2.4 GHz, 2.2 GHz and 200 MHz, respectively. With SMIC 0.13 um process, simulation results show -4.8 dBm of P-1dB compression point and 6 dBm of IIP3 with -10 dBm LO power and IV supply voltage.
Traditional Gilbert cell has been widely used in many mixer circuits, this paper designed a down-conversion mixer which concludes class AB transconductor to improve linearity and LC tank to decrease voltage supply. The RF, LO and IF port frequencies are 2.4 GHz, 2.3 GHz and 100 MHz, respectively. With SMIC 0.18 um process, simulation results show -8dBm of P-ldB compression point and 5 dBm of IIP3...
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.
