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.

機(jī)電類比法是一種把機(jī)械量通過一定的計(jì)算等效類比為電量的方法，其在對電子機(jī)械系統(tǒng)的分析中應(yīng)用非常廣泛。它能夠把一個(gè)較復(fù)雜的機(jī)械系統(tǒng)類比為我們熟知的電路系統(tǒng)來進(jìn)行分析，從而使問題的分析得到簡化。本文通過對振弦式傳感器的分析介紹了機(jī)電類比法，并對使用電路進(jìn)行了相關(guān)的分析。 Summary：The electromechanical analogy is assort of analysis which is to analogize the mechanical system by using circuit system , it applied widely in the filed of analysis the electronic-mechanical system. The analysis can take a complex mechanical system analogous to a circuitry that we well-known, which can simplify the problems. In the paper, the electro-mechanical analogy method is briefly introduced by analysis the vibrating wire sensor，and have a correlation analysis about the circuit we used.關(guān)鍵詞： 機(jī)電類比法 振弦式傳感器 頻率 振蕩 反饋Keyword：electro-mechanical analogy method，vibrating wire sensor，frequency, oscillation, feedback 0 引言振弦式傳感器是屬于頻率式傳感器的一種。所謂頻率式傳感器就是能直接將被測量轉(zhuǎn)換為振動頻率信號的傳感器，這類傳感器一般是通過測量振弦、振筒、振梁、振膜等彈性振體或石英晶體諧振器的固有諧振頻率來達(dá)到測量引起諧振頻率變化的被測非電量的目的，其也稱為諧振式傳感器[1]。在分析該類傳感器中，由于其涉及到頻率，就容易讓人聯(lián)想到在電子技術(shù)中接觸到的RLC振蕩電路。因此可以嘗試著用類比的方法使之對應(yīng)起來分析,即機(jī)電類比法分析。
