摘要：
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 0.18 mu m 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.
