Paper title: 2.4 GHZ LOW POWER UP-CONVERSION MIXER USING NOVEL CURRENT-MIRRORS
Author(s): SHIQIANG CHEN, JUNFENG WANG,
Abstract: A 2.4 GHz CMOS up-conversion mixer using novel current mirrors based on chartered
0.18 μm RF CMOS technology for 2.4 GHz wireless sensor network (WSN) application is
presented in this paper. The current-reuse current-mirror and current-bleeding technique
are used in the driver and switching stages of the mixer, respectively. The post-layout
simulation results demonstrate that the novel up-conversion mixer can provide about
10.5 dB conversion gain with a local oscillator (LO) power of 0 dBm, while the power
consumption is only 0.25 mW with 1 V supply voltage, and the 1 dB compression point
and input-referred third-order intercept point (IIP3) of the mixer are 10.32 dBm and
2.66 dBm, respectively. The chip area including test pads is only 0.5 × 0.6 mm2.
Comparing with the previously reported mixers, the proposed mixer has the advantages
of lower supply voltage, lower power consumption, higher linearity and smaller chip
area than most of the other reported works
