摘要: 本文提出用SPICE軟件模擬pH-ISFET器件及其電路的方法。通過SPICE內(nèi)部的MOSFET參數(shù)和引入一些信號源來實(shí)現(xiàn)對pH-ISFET傳感器及其電路的pH靈敏度關(guān)系、瞬態(tài)響應(yīng)以及溫度特性的模擬,所得結(jié)果與實(shí)驗(yàn)觀測結(jié)果基本相符。

Abstract: 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. -
