Abstract:An improved diversity receiver having a new regulator for stable power supply in a 0.18 lm CMOS technology is presented. The regulator with soft-start is implemented to eliminate the battery damages at initial power-up. To reduce the external components, two switches for antenna diversity are integrated in front of LNA on the chip. A stacked inductor technique is adopted to reduce the chip area. The simulation and measurement results show that the soft-start time of the regulator can be controlled by a variabl… Show more
