Design of ultra-low voltage 0.5V CMOS current bleeding mixer

This paper presents an ultra-low voltage and low power current bleeding CMOS double balanced mixer targeted for ZigBee application in 2.4GHz frequency band. It introduces and discusses a modified CMOS based current bleeding mixer topology adopting a combination of NMOS current bleeding transistor, with a PMOS Local Oscillator (LO) switching stage and integrated inductors to achieve ultra-low voltage headroom operation at 0.5V. This mixer is simulated and verified in 0.13μm standard CMOS technology. The result shows a conversion gain (CG) of 11.84 dB, 1 dB compression point (P1 dB) at −14.36 dBm, third-order intercept point (IIP3) of −5 dBm and a noise figure (NF) of 15 dB and with a power consumption of 930μW.
