Abstract :
In this paper, a low power voltage regulator is presented. The regulator is based on the principle of a resistor-free voltage reference using CMOS transistors in sub-threshold region. An error op-amp is also designed to control the output current flowing through a pass transistor. The voltage regulator was manufactured using the 130 nm ST Microelectronics technology and represents a total area of 0.020 square millimeters. The measured regulated voltage has a temperature coefficient of 49 ppm per Celsius degree and a line regulation of 1.3 mV per Volt. These featured will permit to combine the regulator with a RF-to-DC rectifier´s output voltage to supply a passive RFID temperature sensor.
