摘　　要：基准源是模拟集成电路中的基本单元之一,它在高精度ADC、DAC、SOC等电路中起着重要作用,基准源的精度直接控制着这些电路的精度。本文阐述了一个基于带隙基准结构的低功耗、低温度系数、高电源抑制比的CMOS基准电压源。该电路采用SMIC 0.18μm标准CMOS工艺实现,并用Spectre进行了仿真,得到理想的设计结果。Voltage reference is a basic ceil of analog integrated circuits. It performs an important role in many analog ICs whose precision are controlled by the precision of these cells, such as ADCs. DACs. SOCs and so on. We have designed a CMOS voltage reference circuit with Sub-IV output voltage, lower power, lower temperature coefficient and high PSRR. This circuit was implemented by the standard 0.18μm CMOS technology （SMIC Semiconductor）,we got pretty results afterSpectre simulation.
