Low Power UWB Weak-Inversion Mixer for RF Transceiver

Mohammed Shinas P

A low power ultra wide band down conversion mixer is presented briefly in this paper. In this design, transistors are biased to operate in weak-inversion region so as to reduce the total power consumption of the mixers. The proposed circuit uses source-driven topology and has been designed using 0.18μm standard RF CMOS process. The simulated result shows a total power consumption of 1mW. In addition, under 2V power supply, the proposed mixer gives conversion gain of 21 dB from 1 GHz to 10 GHz, noise figure of 14 dB, OIP3 of -46.9 dBm, IIP3 of 27.7 dBm and 1dB compression gain of -6dBm
