Abstract: Transimpedance amplifiers (TIAs) are widely used to translate the current output of sensors like photodiode-to-voltagesignals, since several circuits and instruments can only accept voltage input. An operational amplifier with a feedback resistor fromoutput to the inverting input is the most straightforward implementation of such a TIA. However, even this simple TIA circuit requirescareful trade-offs among noise gain, offset voltage, bandwidth, and stability. Clearly stability in a TIA is essential for good, reliableperformance. This application note explains the empirical calculations for assessing stability and then shows how to fine-tune theselection of the feedback phase-compensation capacitor.

關(guān)于相位噪聲專題的信息有很多,包括相位噪聲特性1、相位噪聲測量方法2以及它對(duì)系統(tǒng)性能的影響3。眾所周知,振蕩器和時(shí)鐘的相位噪聲已成為導(dǎo)致現(xiàn)代無線電系統(tǒng)性能降低的因素之一。然而,大多數(shù)傳統(tǒng)相位噪聲分析僅將重點(diǎn)放在單載波無線電系統(tǒng)中正弦波信號(hào)的降低,而相位噪聲對(duì)多載波接收機(jī)、寬帶系統(tǒng)或數(shù)字無線電的影響則很少涉及。本應(yīng)用筆記將討論一些與數(shù)據(jù)采樣系統(tǒng)相位噪聲有關(guān)的鮮為人知的問題,主要是多載波無線電、寬帶信號(hào)和欠采樣無線電架構(gòu)等

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

運(yùn)算放大器是線性設(shè)計(jì)的基本構(gòu)建模塊之一。在經(jīng)典模式下,運(yùn)算放大器由兩個(gè)輸入引腳和一個(gè)輸出引腳構(gòu)成,其中一個(gè)輸入引腳使信號(hào)反相,另一個(gè)輸入引腳則保持信號(hào)的相位。運(yùn)算放大器的標(biāo)準(zhǔn)符號(hào)如圖1所示。其中略去了電源引腳,該引腳顯然是器件工作的必需引腳。

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.
