“…Flicker noise of mixers is generated by transconductance stage, switching stage and load stage. Usually, load stage does not have much effect on flick noise [2]- [4], in fact, flicker noise of the transconductance stage is converted to LO frequency. So flick noise of the mixer is mainly determined by the switching stage.…”

“…Some researches have considered the conventional current bleeding mixer [1]- [4], the static current bleeding technique was proposed to reduce the bias current of the LO switches [5] - [7].This is to reduce the bias current of the LO switches (direct mechanism of flicker noise), but the effects of the tail capacitance can not be reduced (indirect mechanism of flicker noise). And during the charging and discharging of the parasitic capacitance, the switch stage will generate large flicker noise [8].…”

An improved current bleeding CMOS mixer is designed in this paper. The conversion gain of the mixer is increased and the flicker noise of the mixer is reduced by inserting the inductor to form resonant circuit with parasitic capacitors of the source ports of the switch transistors in Gilbert mixer. The mixer is designed by using SMIC 0.18 um CMOS process. The simulated results show that the mixer proposed has a 1.76dB increase of conversion gain, 2.1dBm improvement of IIP3, 0.5dB decrease of noise figure with local power of -3 dBm as compared with the mixer before inserting the inductor.

This paper presents the designed and measured performance of a Global Positioning System (GPS) receiver chain integrated as a part of a multi-band and multimode receiver, designed for global system for mobile communications (GSM) and wideband code division multiple access (WCDMA). Adding an additional mode to a receiver with minor changes to the implementation is discussed. The IC is implemented in a 0.13-µm CMOS technology without any analog options. At 1.2-V supply voltage and total power dissipation of 49 mW for the analog signal path, the proposed GPS receiver features a noise figure of 2.2 dB.

This paper presents an integrated quadrature demodulator with on-chip frequency divider implemented in a 0.13 µm CMOS technology. The mixer consists of a transconductance stage, a passive current switching stage, and an operational amplifier output stage. A complementary input architecture has been used to increase the transconductance for a given bias current. From 700MHz to 2.5GHz, the demodulator achieves 10dB DSB NF with 9-33 kHz 1/f-noise corner and 35dB of low frequency voltage gain. The total chip draws 20mA-24mA from a single 1.5V supply.
