| 摘 要： | 提出了一种新的基于改进的电流模式带隙基准源的可编程基准源的设计与实现方法.电路采用Chartered 0.35μm 工艺仿真并流片.测试结果表明,温度变化范围为0～100℃,温度系数为±36.3ppm/℃(VID=11110).电源电压变化范围为2.7～5V,其相对变化值为5mV.当VID0频率为125kHz时,瞬态响应最大毛刺幅度约为20mV.5位VID码不同的输入状态,输出基准电压从1.1变到1.85V,变化步长为25mV.

| Abstract: | A new approach for the design and implementation of a programmable voltage reference based on an improved current mode bandgap voltage reference is presented.The circuit is simulated and fabricated with Chartered 0.35μm mixed-signal technology.Measurements demonstrate that the temperature coefficient is ±36.3ppm/℃ from 0 to 100℃ when the VID inputs are 11110.As the supply voltage is varied from 2.7 to 5V,the voltage reference varies by about 5mV.The maximum glitch of the transient response is about 20mV at 125kHz.Depending on the state of the five VID inputs,an output voltage between 1.1 and 1.85V is programmed in increments of 25mV. |
