Abstract:

Based on the problem that the accuracy of the bandgap affects the performance of the integrated circuit, a novel BGR (bandgap voltage reference) is proposed. It utilizes a feedback compensation network to enhance PSRR and reduce the offset voltage, which improves the system stability and precision. Cadence spectre simulation has been done by the SMIC 018μm 1.8V CMOS process for validation. The results show that the achieved temperature coefficient is 34.6×10^-6/℃ over -30℃ to 100℃ and that the PSRR is -63.5dB at a low frequency. The power assumption is only 1.5μW. The circuit is suitable for a low-voltage low-power energy harvesting system.

Key words: bandgap voltage reference, power supply rejection ratio, low-offset, low-power
