Abstract
An exponential curvature-compensated bandgap reference(BGR), which is designed in 0.18μm CMOS process, is proposed in this paper. The Darlington transistor structure is applied to reduce offset voltage of Amplifier, and a CTAT current circuit is used to generate the current with the higher order. To meets the needs of ADC, the noise of BGR is reduced by RC filter. Simulated in the 0.18μm DBH technology, the proposed BGR can achieve a total output noise of 9.54μv between 0.1 Hz and 1G with a filter capacitor of 5pF. A temperature coefficient of 2.1-ppm/°C is achieved by using exponential curvature-compensated at typical corner, and the temperature coefficient is less than 5-ppm/°C in all processes.
