摘要
本文提出用SPICE软件模拟pH-ISFET器件及其电路的方法。通过SPICE内部的MOSFET参数和引入一些信号源来实现对pH-ISFET传感器及其电路的pH灵敏度关系、瞬态响应以及温度特性的模拟,所得结果与实验观测结果基本相符。
A simulation method with SPICE for pH-ISFET based sensors and their circuits is
presented. Using the parameters of built-in MOSFET in SPICE and some voltage sources, pH versus sensitivity, transient response and temperature characteristic of pH-ISFET based sensors and their circuits are carried out and corresponded to experimental results.
