Abstract

In this paper, a double-balanced folded-switching mixer with ultra low current consumption for DCR of wireless communication applications is presented. This mixer is with improved RF Gm stage adopting the current-reuse and ac-coupling technologies. With the TSMC 0.18-μm 1- Poly 6-Metal RF CMOS process, the proposed mixer topology can achieve 0.85dBm IIP3, 4.8dB conversion gain under 1.2V supply voltage with 1.2mA current consumption. When the supply voltage decreases to 1V, the mixer can achieve -0.53dBm IIP3, 1 dB conversion gain with 1.3mA current consumption.
