A Sub-1V High-PSRR Piecewise-Linear Bandgap Reference

A piecewise-linear bandagp reference (BGR) with high power supply rejection ratio (PSRR) and low temperature coefficient is designed for analogue and mixed signal systems in this paper. By adopting LDO regulator, the designed high PSRR piecewise-linear BGR achieves well performances and has a simple architecture. Simulation results show that the PSRR of the designed piecewise-linear BGR with LDO regulator at 10Hz, 1kHz and 100kHz achieves, respectively, -110.42dB, -109.18dB and -64.51dB. Compared to the designed BGR without LDO regulator, the PSRR of the designed high PSRR piecewise-linear BGR with LDO regulator has the improvements of about 35dB, 36.9dB and 29.28dB at 10Hz, 1kHz and 100kHz respectively. The designed piecewise-linear BGR with LDO regulator generates an output voltage of 0.68V with 1.65ppm/oC temperature coefficient in the range from -50 oC to 125 oC. The deviation of the output voltage is within 98.23μV when the power supply voltage V DD changes from 1.2V to 7V.
