Abstract

A low-voltage and high-linearity downconverter RFIC design using TSMC 0.18 μm CMOS foundry for WiMAX applications is presented in this paper. The LC resonator is used to block DC and RF signals for low supply voltage and the multiple-gated CMOS is adopted to eliminate third-order nonlinear term for high linearity. The crucial simulated results of WiMAX downconverter include that a conversion gain is 5.3 dB, an input 1 dB compression point (IP_1dB) is -9 dBm, an input third-order intercept point (IIP₃) is 1 dBm, and a noise figure (NF) is 12.2 dB. The supply voltage of 0.8 V is used and the power consumption is equal to 8 mW.
