  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 invert ...

  A fully differential amplifi er is often used to converta single-ended signal to a differential signal, a designwhich requires three signifi cant considerations: theimpedance of the single-ended source must match thesingle-ended impedance of the differential amplifi er,the amplifi er&rsqu ...

  Recent advances in low voltage silicon germaniumand BiCMOS processes have allowed the design andproduction of very high speed amplifi ers. Because theprocesses are low voltage, most of the amplifi er designshave incorporated differential inputs and outputs to regainand maximize total outp ...

  This application note is an overview discussion of theLinear Technology SPICE macromodel library. It assumeslittle if any prior knowledge of this software library or itshistory. However, it does assume familiarity with both theanalog simulation program SPICE (or one of its manyderivatives ...

  This publication represents the largest LTC commitmentto an application note to date. No other application noteabsorbed as much effort, took so long or cost so much.This level of activity is justified by our belief that high speedmonolithic amplifiers greatly interest users.

This note describes some of the unique IC design techniques incorporated into a fast, monolithic power buffer, the LT1010. Also, some application ideas are described such as capacitive load driving, boosting fast op amp output current and power supply circuits.

Application considerations and circuits for the LT1001 and LT1002 single and dual precision amplifiers are illustrated in a number of circuits, including strain gauge signal conditioners, linearized platinum RTD circuits, an ultra precision dead zone circuit for motor servos and other examples.

能实现VCO 功能的电路很多，常用的有分立器件构成的振荡器和集成压控振荡器。如串联谐振电容三点式电路、压控晶体振荡器，积分-施密特电路、射级耦合多谐振荡器、变容二极管调谐LC 振荡器和数字门电路等几种。它们之间各有优缺点，下面做简要分析，并选择最合适的方案。 ...

  噪声系数(NF)是RF系统设计师常用的一个参数，它用于表征RF放大器、混频器等器件的噪声，并且被广泛用作无线电接收机设计的一个工具。许多优秀的通信和接收机设计教材都对噪声系数进行了详细的说明(例如参考文献1)，本文重点讨论该参数在数据转换器中的应用。 ...

提出了一种应用于CSTN-LCD系统中低功耗、高转换速率的跟随器的实现方案。基于GSMC±9V的0.18 μm CMOS高压工艺SPICE模型的仿真结果表明，在典型的转角下，打开2个辅助模块时，静态功耗约为35 μA；关掉辅助模块时，主放大器的静态功耗为24 μA。有外接1 μF的大电容时，屏幕上的充放电时间为10 μs；没有外接1μF的大电容时 ...
