A low power CMOS low noise amplifier for wireless communications

摘要

A low power CMOS low noise amplifier (LNA) working at 2.4 GHz for wireless communications is presented in this paper, by using TSMC 0.18 μm technology. The current reused architecture is adapted to reduce the consumed current, while the supply voltage is set to 0.6 V to meet the low-voltage requirement as well. To simplify the bias network designs under low-voltage operations, NMOS and PMOS devices are utilized with three-stage configuration to enhance the gain performance. The measured results show 17.7 dB in gain and 3.9 dB in noise figure with 0.86 mW of power consumption.
