| 摘 要： | 该文设计的可程控参考电压源电路,具有低温度系数、高电源抑制比、范围可调的性能;设计由外部输入数字信号而转换为芯片内部的参考信号的开关电阻分压电路,不仅提供了与转换相对应的参考电压,还提供了整个芯片其他电路所需的基准电压。这种电路可广泛地应用在可程控微电路中,通过Mutisim2001仿真和实验,得到较好的电压输出特性。

| Abstract: | The design of programmable voltage reference circuit must be with low temperature coefficient,high power supply rejection ratio,range adjustable performance.One designed externally imputed digital signal and converted the reference signal chip resistor divider switch circuit,which did not only provide conversion correspond to the table with a reference voltage,but also provides other required reference voltage circuit.This circuit can be widely used in micro-circuits can be programmed through the Multisim2001 simulation and experiment,get a better voltage output characteristics. |
