A tutorial on SAR type A/D converters, this note contains detailed information on several 12-bit Circuits. Comparator, clocking, and preamplifier designs are discussed. A final circuit gives a 12-bit conversion in 1.8µs. Appended sections explain the basic SAR technique and explore D/A considerations.

Low power operation of electronic apparatus has becomeincreasingly desirable. Medical, remote data acquisition,power monitoring and other applications are good candidatesfor battery driven, low power operation. Micropoweranalog Circuits for transducer-based signal conditioningpresent a special class of problems. Although micropowerICs are available, the interconnection of these devices toform a functioning micropower circuit requires care. (SeeBox Sections, “Some Guidelines for Micropower Designand an Example” and “Parasitic Effects of Test Equipmenton Micropower Circuits.”) In particular, trade-offs betweensignal levels and power dissipation become painful whenperformance in the 10-bit to 12-bit area is desirable.

Over the past several years Linear Technology, the magazine, has come of age. From nothing, the publication has come into its own, as has its subscriber list. Many innovative Circuits have seen the light of day in the pages of our now hallowed publication.

Construction Strategy of ESD Protection CircuitAbstract： The principles used to construct ESD protection on Circuits and the basic conceptions of ESD protection design are presented.Key words：ESD protection/On circuit, ESD design window, ESD current path1 引言靜電放電（ESD，Electrostatic Discharge）給電子器件環(huán)境會(huì)帶來(lái)破壞性的后果。它是造成集成電路失效的主要原因之一。隨著集成電路工藝不斷發(fā)展，互補(bǔ)金屬氧化物半導(dǎo)體（CMOS，Complementary Metal-Oxide Semiconductor）的特征尺寸不斷縮小，金屬氧化物半導(dǎo)體(MOS, Metal-Oxide Semiconductor)的柵氧厚度越來(lái)越薄，MOS 管能承受的電流和電壓也越來(lái)越小，因此要進(jìn)一步優(yōu)化電路的抗ESD 性能，需要從全芯片ESD 保護(hù)結(jié)構(gòu)的設(shè)計(jì)來(lái)進(jìn)行考慮。

OPTOELECTRONICS CIRCUIT COLLECTION AVALANCHE PHOTODIODE BIAS SUPPLY 1Provides an output voltage of 0V to +80V for reverse biasingan avalanche photodiode to control its gain. This circuit canalso be reconfigured to supply a 0V to –80V output.LINEAR TEC DRIVER–1This is a bridge-tied load (BTL) linear amplifier for drivinga thermoelectric cooler (TEC). It operates on a single +5Vsupply and can drive ±2A into a common TEC.LINEAR TEC DRIVER–2This is very similar to DRIVER–1 but its power output stagewas modified to operate from a single +3.3V supply in orderto increase its efficiency. Driving this amplifier from astandard +2.5V referenced signal causes the output transistorsto have unequal power dissipation.LINEAR TEC DRIVER–3This BTL TEC driver power output stage achieves very highefficiency by swinging very close to its supply rails, ±2.5V.This driver can also drive ±2A into a common TEC. Operationis shown with the power output stage operating on±1.5V supplies. Under these conditions, this linear amplifiercan achieve very high efficiency. Application ReportThe following collection of analog Circuits may be useful in electro-optics applications such as optical networkingsystems. This page summarizes their salient characteristics.

Radio Frequency Integrated Circuit Design I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic Circuits andtransmission lines. Most analog integrated circuit designers in the past workedon applications at low enough frequency that microwave issues did not arise.As a consequence, they were adept at lumped parameter Circuits and often notcomfortable with Circuits where waves travel in space. However, in order todesign radio frequency (RF) communications integrated Circuits (IC) in thegigahertz range, one must deal with transmission lines at chip interfaces andwhere interconnections on chip are far apart. Also, impedance matching isaddressed, which is a topic that arises most often in microwave Circuits. In mycareer, there has been a gap in comprehension between analog low-frequencydesigners and microwave designers. Often, similar issues were dealt with in twodifferent languages. Although this book is more firmly based in lumped-elementanalog circuit design, it is nice to see that microwave knowledge is brought inwhere necessary.Too many analog circuit books in the past have concentrated first on thecircuit side rather than on basic theory behind their application in communications.The Circuits usually used have evolved through experience, without asatisfying intellectual theme in describing them. Why a given circuit works bestcan be subtle, and often these Circuits are chosen only through experience. Forthis reason, I am happy that the book begins first with topics that require anintellectual approach—noise, linearity and filtering, and technology issues. Iam particularly happy with how linearity is introduced (power series). In therest of the book it is then shown, with specific Circuits and numerical examples,how linearity and noise issues arise.
