  • 理想的电压反馈型(VFB)运算放大器

    &Nbsp; 运算放大器是线性设计的基本构建模块之一。在经典模式下,运算放大器由两个输入引脚和一个输出引脚构成,其中一个输入引脚使信号反相,另一个输入引脚则保持信号的相位。运算放大器的标准符号如图1所示。其中略去了电源引脚,该引脚显然是器件工作的必需引脚。

  • 数字集成电路设计Digital Integrated Circuit Design

    &Nbsp; This unique guide to designing digital VLSI circuits takes a top-down approach, reflecting the natureof the design process in industry. Starting with architecture design, the book explains the why andhow of digital design, using the physics that designers need to know, and no more.Covering system and component aspects, design verification, VHDL modelling, clocking, signalintegrity, layout, electricaloverstress, field-programmable logic, economic issues, and more, thescope of the book is singularly comprehensive.

  • ADC需要考虑的交调失真因素

    &Nbsp; 交调失真(IMD)是用于衡量放大器、增益模块、混频器和其他射频元件线性度的一项常用指标。二阶和三阶交调截点(IP2和IP3)是这些规格参数的品质因素,以其为基础可以计算不同信号幅度下的失真积。虽然射频工程师们非常熟悉这些规格参数,但当将其用于ADC时往往会产生一些困惑。本教程首先在ADC的框架下对交调失真进行定义,然后指出将IP2和IP3的定义应用于ADC时必须采取的一些预防措施。

  • 小面积和大面积光电二极管的低噪声放大器

    &Nbsp; Photodiodes can be broken into two categories: largearea photodiodes with their attendant high capacitance(30pF to 3000pF) and smaller area photodiodes withrelatively low capacitance (10pF or less). For optimalsignal-to-noise performance, a transimpedance amplifi erconsisting of an inverting op amp and a feedback resistoris most commonly used to convert the photodiode currentinto voltage. In low noise amplifi er design, large areaphotodiode amplifi ers require more attention to reducingop amp input voltage noise, while small area photodiodeamplifi ers require more attention to reducing op amp inputcurrent noise and parasitic capacitances.

  • 西门子S7-200 CPU PID控制图解

    PID控制器由比例单元(P)、积分单元(I)和微分单元(D)组成。其输入e (t)与输出u (t)的关系为 u(t)=kp[e(t)+1/TI∫e(t)dt+TD*de(t)/dt] 式中积分的上下限分别是0和t 因此它的传递函数为:G(s)=U(s)/E(s)=kp[1+1/(TI*s)+TD*s] 其中kp为比例系数; TI为积分时间常数; TD为微分时间常数. &Nbsp;
