Abstract :
This paper presents the analysis and design of a highly linear fully differential LNA based on the modification of active post distortion method. The analysis focuses on both nonlinearity and noise performance. The linearisation mechanism is investigated in terms of low frequency and high frequency theory based on Power and Volterra series respectively. A prototype LNA has been designed and is to be implemented in UMC 0.18 μm CMOS technology. Simulation shows the LNA achieves 9.7 dBm IIP3 with 16.5 dB power gain, 1.97 dB noise figure and 15.84 mW power consumption.
