A Bandgap Reference without Passive Components Based on Standard CMOS

Abstract:

A bandgap reference without passive components based on standard CMOS is proposed. Using an improved inverse-function technique without any curvature-compensated techniques, two reference voltages are got in different temperature ranges. One is 1.56V with a temperature coefficient of 9.2ppm/°C in the range [0, 14 °C at 3.3V supply voltage, and the other is 1.546V with 47ppm/°C in [-25, 15 °C at 3.3V. Its PSRR (power supply rejection ratio) is below-60dB at 10kHz, and it is quite suitable for integration in processing circuits of MEMS (micro-electro-mechanical systems) devices.
