Abstract :
Design description and measurement results of 0.18 mum CMOS direct conversion receiver front-end intended for use in a transceiver for 2.4 GHz band of 802.15.4 standard are presented. Front-end consists of LNA and two current-mode passive mixers. Single-ended RF drive of double-balanced I/Q mixers was used as a means of power dissipation reduction. The measurement showed the following performance: noise figure 7.3 dB, 1/f-noise corner 70 kHz, power gain 10 dB, input IP3 -8 dBm with DC current dissipation of 3.5 mA while operating from voltage supply of 1.8 V
