Abstract
This paper presents a low flicker noise RF CMOS mixer using TSMC0.13-μm technology for 2.4 GHz wireless communication systems. Proposed design is based on a doubly balanced Gilbert cell mixer type with a charge injection technique and a tuning inductor. The proposed mixer presents a low flicker noise, high input matching, high linearity with a low power consumption and low noise figure. The simulated results using Agilent's Advanced Design System (ADS2009) software show that the proposed mixer achieves 7.4 dB SSB-NF, 12.8 dB conversion gain, 0 dBm IIP3, and flicker noise (1/f) corner frequency of 32.6 kHz with 2.8 mW power consumption from 1.3V supply voltage. The proposed design demonstrates better performance in linearity, higher conversion gain and lower noise figure compared to conventional mixer designs.
