Abstract :
A regulator is designed for radio-frequency identification tags in the ultrahigh-frequency band using the Taiwan Semiconductor Manufacturing Company 0.18-¿m CMOS process. A stable reference voltage with short calibration time is designed by integrating a ripple stabilizer and a temperature stabilizer. The regulator output exhibits a line regulation and load regulation of 12 mV/V and 0.34 mV/mA, respectively, and its power supply rejection ratio is 35.1 dB at 1 MHz.
