Who has never experienced oscillations issues when using an OPerational amplifier? OPampsare often used in a simple voltage follower configuration. However, this is not the bestconfiguration in terms of capacitive loading and potential risk of oscillations.Capacitive loads have a big impact on the stability of OPerational amplifier-basedapplications. Several compensation methods exist to stabilize a standard OP-amp. Thisapplication note describes the most common ones, which can be used in most cases.The general theory of each compensation method is explained, and based on this, specific

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.

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), and modern day OP amps, including bipolar,JFET, and MOSFET amplifier technologies

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.

本文将接续介绍电源与功率电路基板，以及数字电路基板导线设计。宽带与高频电路基板导线设计a.输入阻抗1MHz，平滑性(flatness)50MHz 的OP增幅器电路基板图26 是由FET 输入的高速OP 增幅器OPA656 构成的高输入阻抗OP 增幅电路，它的gain取决于R1、R2，本电路图的电路定数为2 倍。此外为改善平滑性特别追加设置可以加大噪讯gain，抑制gain-频率特性高频领域时峰值的R3。图26 高输入阻抗的宽带OP增幅电路图27 是高输入阻抗OP 增幅器的电路基板图案。降低高速OP 增幅器反相输入端子与接地之间的浮游容量非常重要，所以本电路的浮游容量设计目标低于0.5pF。如果上述部位附着大浮游容量的话，会成为高频领域的频率特性产生峰值的原因，严重时频率甚至会因为feedback 阻抗与浮游容量，造成feedback 信号的位相延迟，最后导致频率特性产生波动现象。此外高输入阻抗OP 增幅器输入部位的浮游容量也逐渐成为问题，图27 的电路基板图案的非反相输入端子部位无full ground设计，如果有外部噪讯干扰之虞时，接地可设计成网格状(mesh)。图28 是根据图26 制成的OP 增幅器Gain－频率特性测试结果，由图可知即使接近50MHz频率特性非常平滑，-3dB cutoff频率大约是133MHz。

Abstract: We can apply a BiCMOS integrated circuit with only resistors and no transistors to solve adifficult design problem. The mythically perfect OPerational amplifier's gain and temperature coefficient aredependent on external resistor values. Maxim precision resistor arrays are manufactured together on asingle die and then automatically trimmed, to ensure close ratio matching. This guarantees that theOPerational amplifier (OP amp) gain and temperature coefficient are predictable and reliable, even withlarge production volumes.
