大多数实用传感器的输入输出特性分为两类：I 类，其特性呈指数上升；II 类，其特性呈指数衰减。虽然类型 I 使用对数转换器可以轻松实现线性化，但类型 II 需要额外的反演装置才能实现线性化。提出了一种使用对数转换器和 FET 线性化 II 型传感器特性的技术，并将其性能与简单的单冲程数字技术的性能进行了比较。给出并讨论了示例和实验结果。<>
Most of the practical transducers fall into two categories regarding their input-output characteristics: type I, with a characteristic that is exponentially rising, and type II, with a characteristic that is exponentially decaying. While type I is easily linearized using a logarithmic converter, type II needs additional inversion means for the purpose of linearization. A technique for linearizing type-II transducer characteristic using a log-converter and a FET is presented, and its performance is compared with that of a simple single-stroke digital technique. Examples and experimental results are presented and discussed.<>
