A High-conversion Gain, Low-power Mixer Adapting Current Reuse Technique for ZigBee Application.

This paper presents a high-conversion gain, low-power, folded CMOS mixer for ZigBee application in 2.4 GHz of userbandwidth. The proposed mixer adapts current reuse technique to increase the conversion gain while substantiallyreducing the DC power dissipation. The current from LO stage is reused at the transconductance stage to reduce thepower consumption. This mixer is verified in 0.13 µm standard CMOS technology. The simulation result exhibits ahigh-conversion gain performance (CG) of 10 dB, 1 dB compression point (P1 dB) of -13.43 dBm, third-order interceptpoint (IIP3) of -4.3 dBm, and a noise figure of 16.67 dB. The circuit draws 675 µA current from the 1.2 V of supplyvoltage headroom. [ABSTRACT FROM AUTHOR]
