Abstract :
A low power variable gain RF front-end is designed and fabricated in 0.25 mum CMOS technology. Power consumption can be reduced by sharing current between cascode LNA and mixer. The power consumption of designed RF front-end is 11.3 mW with 2.5 V supply voltage. Also, gain of the RF front-end is varied from 14.5 to 30.5 dB by changing the load impedance of LNA
