摘要
采用二级温度补偿对传统电流模式结构的带隙基准电压电路进行改进,基于chartered 0.35um cmos工艺,使用cadence spectre进行仿真,结果表明工作电压为2v时,电路可以输出100mv—1.8v的宽范围电压;在-20-120温度范围内,平均温度系数约3ppm/°C。
A 2nd order temperature compensation bandgap reference circuit is designed here based on the conventional 1st order temperature compensation circuit with current-mode. Based on Chartered 0.35um CMOS process, it＇s simulated by cadence spectre . Rsults show that with 2v supply voltage, the Bandgap Reference has a wide output from 100mv to 1.8v. At the same time, an average temperature coefficient about 3ppm/oC is got at the temperature extension from -20-120.
