Abstract
A fully integrated 5.2GHz variable gain low noise amplifier (VGLNA) in a 0.18μm CMOS process is proposed in this paper. The VGLAN can achieve a maximum small signal gain of 17.85 dB within the noise figure (NF) of 2.04 dB and a minimum gain of 2.04 dB with good input return loss. The LNA’s P1dB in the high gain mode is -17.5 dBm. The LAN consumes only 14.58 mW from a 1.8V power supply.
