摘    要:通过对电压源传统设计中关于速度、噪声、工作温度范围方面的研究,设计了一种带隙基准电压源.基于TSMC工艺套件的电路模拟仿真表明,该电路可在1.5~1.8V电压下正常工作,功耗小于0.5 mW,输出电压为1.25V,温度系数低于1.8×10~(-5)/℃,且低频下PSRR的值可以达到-110 dB.

关 键 词:CMOS  带隙基准电压源  工作温度范围  电源抑制比  温度系数

Abstract:A bandgap voltage reference has been proposed.We have provided improvements on speed,noise, temperature operating range issues compared with traditional bandgap reference design.Validity and accuracy of this scheme are verified by TSMC Process-Design-Kit-Based simulations.Simulation Results proved that this circuit can work at 1.5~1.8 V supply with power consumption less than 0.5 mW,the output reference voltage is 1.25 V,temperature coefficient is less than 1.8×10~(-5)℃and PSRR is-110 dB at DC.This cir- cuit can be widely applied to portable electronic designs.
Keywords:CMOS
