Abstract :
A CMOS direct-conversion receiver including a low noise amplifier and a novel single transistor stacked mixer is proposed in this paper. The LNA has a small signal gain of 12∼10 dB and a noise figure of 4.2∼4.8 dB in 3∼7 GHz range. The conversion gain and the input P1dB of the mixer are 3∼6.5 dB and -10 dBm, respectively with the multiband RF signals. The LNA consumes 9.2 mA and the mixer consumes 4.3 mA under 1.8 V supply voltage, respectively.
