| 摘 要： | 传统设计中平衡温度时的带隙基准电压值是与工艺相关联的定值.主要基于通用的带隙技术讨论在CMOS工艺中基准产生的设计,在对基准产生原理与传统电路结构分析的基础上,设计出一种高PSRR输出可调带隙基准电压源.电路综合温度补偿、电流反馈和电阻分压技术,采用CSMC 0.5 tim CMOS混合信号工艺实现,并用Cadence的Spectre进行了仿真优化.仿真结果表明,带隙基准电压源在-15～80℃范围内输出为603.5 mV时的温度系数为6.84 × 10-6/℃,在1.8～5 V电路均可正常工作.流片后的测试结果验证了该方法的可行性,基准电压中心值可宽范围调整,各项性能参数满足设计要求.
