【 摘 要 】

High gain, low noise, and low power 920-MHz LNA has been studied. To realize both low noise and low power characteristics, the transistor has to be operated in the moderate inversion region, and to complement gain reduction due to moderate inversion operation, a current-reuse amplifier topology consisting of a vertically stacked cascaded two-stage cascode circuit is designed. The measurement results exhibit S21 of 15.1dB, NF of 2.56dB under a supply voltage of 0.8V, and power consumption of 1.28mW. The process technology used in this study is TSMC 180nm CMOS.
