A Low Temperature Coefficient and Low Power 4th-Order Curvature Compensated Bandgap Reference

TAN Yulin;FENG Quanyuan;Institute of Microelectronics,Southwest Jiaotong University;  
Based on UMC 0.25μm BCD technology,a low temperature coefficient and low power consumption bandgap reference with 4th-order curvature compensation was proposed.The 4th-order curvature compensation was achieved by using the ratio of resistance with different positive temperature coefficient and negative temperature coefficient to counteract the high-order items of the emitter-base voltage expanded in Taylor series.By simulation and verification with HSPICE,the circuit achieved an output voltage of 1.196 V,a temperature coefficient of 1.43×106/℃in the temperature range of-40 ℃to 150 ℃,a PSRR of-70.8dB at low frequency and a linear regulation of0.039%in the power supply voltage range of 1.7Vto 5V.The total quiescent current was only 9.8μA.
