Temperature compensation design for a 2.4 GHz CMOS low noise amplifier

摘要

In this paper, a low noise amplifier suitable for wireless WCDMA systems is designed with AMS 0.35 /spl mu/m CMOS process. A biasing circuit with temperature compensation is presented. The simulation result in Cadence shows that the LNA can achieve 12.7 dB power gain and 1.7 dB noise figure with 7 mW power consumption at 27/spl deg/C. The gain and NF variations over -45/spl deg/C to 85/spl deg/C are less than 0.4 dB and 0.1 dB respectively.
