Abstract

In this paper a low flicker-noise highly linear 5 GHz direct conversion receiver (DCR) has been proposed. A dynamic current injection (DCI) technique has been utilized in addition with a tuning inductor for output flicker noise (1/f) reduction. Derivative superposition (DS) technique has been used in the mixer circuit to enhance the linearity. The DCR has been designed and fabricated using TSMC 0.18μm 1P6M CMOS technology. The proposed DCR achieves 7.2dB SSB-NF, 25dB conversion gain, 4dBm IIP3, and flicker noise corner frequency of 100KHz with 72mW power consumption from 1.8V supply voltage.
