[通用技术]如何在SPICE中构建铂RTD传感器模型
【导读】KWIK（技术诀窍与综合知识）电路应用笔记提供应对特定设计挑战的分步指南。对于给定的一组应用电路要求，本文说明了如何利用通用公式应对这些要求，并使它们轻松扩展到其他类似的应用规格。该传感器模型支持对电阻温度检测器(RTD)的电气和物理特性进行SPICE仿真。SPICE模型使用了描述RTD（其将温度转化为电阻）物理行为特性的参数。它还提供了一个典型的激励和信号调理电路，利用该电路可演示RTD模型的行为。 RTD概述 RTD是阻性元件，其电阻随温度变化而变化。RTD的行为已为人所熟知，可用于进行精密温度测量，精度可达0.1°C以下
[RF/微波]QSPICE发明者随笔——利用宽带隙FET简化高压调节
【导读】Charley Moser拥有EE博士学位，是我最早的模拟设计导师之一。从他那里，我学到了很多知识——混合pi晶体管建模、用于稳定性分析的Bode图对最小相位系统的限制、为什么要使用缓冲器以及如何设计缓冲器、防止击穿的双极基极拉电流、SCR在高温下的使用等。其中，如何在高电压下调节低功率是最引人注目的创新；这对我来说极具价值，因为我是多家仪器公司带电粒子光学方案中所用高压电源设计领域的高手。 他教我用接地基极高压晶体管进行并联调节，并通过运算放大器驱动发射极。晶体管的增益带宽将在其fT下降低3dB。用低电压输入控制高
