CMOS Even Harmonic Switching Mixer for Direct Conversion Receivers

Abstract

DC offset and high flicker noise are the main problems for the direct conversion CMOS mixer design. A novel even harmonic switching mixer implemented in a standard 0.18µm CMOS process for applications in 2.45GHz direct conversion receivers is proposed. The mixer circuit overcomes the problems of DC offset and high flicker noise. It achieves -8.24dB gain, 5.2dB DSB noise figure at 100KHz, 17.25dBm IIP3 and zero DC power consumption.
