摘　　要：基于90 nm CMOS标准工艺,设计了一种低温漂的带隙基准源电路。一种结构新颖的温度曲率校正电路被采用,作为一级温度补偿电路的曲率校正电路。Hspice仿真结果表明:所设计电压源在温度-20℃^+120℃范围内,平均温度系数约为2.2 ppm/℃,获得了一个低压高精度的带隙基准电压源。The design of the novel currature correction temperature compensation bandgap reference circuit as the currature cor- rection circuit of the first order temperature compensation bandgap reference circuit, and get a better output and lower average tem- perature coefficient, which is fabricated with 90 nm CMOS technology. Result from HSPICE simulation shows that the circuit has an average temperature coefficient about 2.2 ppm/℃ between -20 ℃ to 120 ℃.

关 键 词：带隙基准源 温度系数 曲率校正
