Abstract

Based on the analysis of the conventional bandgap reference circuitry and the current IC of reference voltage source in the design of low voltage low power consumption and high power supply rejection ratio, a bandgap voltage reference with startup circuit and current compensation circuit is presented. It has a low temperature coefficient(<20ppm/℃)，a temperature coefficient of 9.3ppm/℃ in the temperature range from-50℃ to 125℃, and a PSRR of-64dB at low frequency,which meets the requirements of bandgap reference for low voltage, low power and high PSRR.
