An ultra-low power voltage regulator for RFID application

This paper presents a low power regulator design for RFID application using 65nm CMOS technology. The design consists of two parts: a reference generator with temperature compensation, and a low power LDO regulator. Most of MOSFET transistors in the design operate at subthreshold region for low power dissipation. Simulation results show that the proposed regulator is capable of operating within a wide range of supply voltage (from 1.1V to 2.5V) and temperature (from -30°C to 50°C), with the total quiescent current of as low as 63.8nA at room temperature.
