Abstract
An RF mixer with high linearity for 2.4 GHz ISM band applications is presented. The mixer is composed of a modified class-AB transconductor stage and a common mode feedback (CMFB) circuitry. With this topology the following simulation results are achieved: input 1-dB compression point (P-1dB) -8.98 dBm, input third-order intercept point (IIP3) 5.46 dBm, power conversion gain 3.3 dB, and single side-band noise figure 14.87 dB. The mixer implemented by tsmc 0.18 mum CMOS process consumes 3.73 mA of current from a 1.5 V power supply
