Abstract

In this paper, a low flicker-noise, 2.4 GHz direct onversion receiver (DCR) has been designed. A dynamic current injection (DCI) technique has been utilized in addition with a tuning inductor in the mixing stage. The tuning inductor has been replaced by a differential active inductor circuit, which gives the same inductance, with less chip size and high quality factor. The DCR has been designed in a TSMC 0.18 μm 1P6M CMOS process for wireless LAN 802.11g applications. The proposed DCR achieves 6.7 dB SSB-NF, 34 dB conversion gain, -13.5 dBm IIP3, and flicker noise (1/f) corner frequency of 30 kHz with 137.5 mW power consumption from 1.8 V supply voltage.
