摘要:

设计了一款带隙基准电压源,基于0.18 μm的CMOS工艺,在Hspice下仿真,仿真结果表明,温度在-25~ 80 ℃内变化时,温度系数为9.14×10-6 ℃;电源电压在3~5 V之间变化时,基准电压在1 250±43 mV 内变化,满足设计要求。

关键词: 带隙基准, 温度系数, 互补金属氧化物半导体(CMOS)

Abstract:

By using 0.18 μm complementary metal oxide semiconductor (CMOS) model,a bandgap reference circuit is designed.The circuit is simulated by Hspice.When operating at a 5 V power supply with the temperature range from -25 to 80 ℃,the device has a temperature coefficient of 9.14×10-6 ℃.It outputs a voltage of 1 250±43 mV at room temperature,when the power supply varies from 3 V to 5 V.

Key words: bandgap reference;temperature coefficient;complementary metal oxide semiconductor (CMOS)
