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.

机电类比法是一种把机械量通过一定的计算等效类比为电量的方法，其在对电子机械系统的分析中应用非常广泛。它能够把一个较复杂的机械系统类比为我们熟知的电路系统来进行分析，从而使问题的分析得到简化。本文通过对振弦式传感器的分析介绍了机电类比法，并对使用电路进行了相关的分析。 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.关键词： 机电类比法 振弦式传感器 频率 振荡 反馈Keyword：electro-mechanical analogy method，vibrating wire sensor，frequency, oscillation, feedback 0 引言振弦式传感器是属于频率式传感器的一种。所谓频率式传感器就是能直接将被测量转换为振动频率信号的传感器，这类传感器一般是通过测量振弦、振筒、振梁、振膜等弹性振体或石英晶体谐振器的固有谐振频率来达到测量引起谐振频率变化的被测非电量的目的，其也称为谐振式传感器[1]。在分析该类传感器中，由于其涉及到频率，就容易让人联想到在电子技术中接触到的RLC振荡电路。因此可以尝试着用类比的方法使之对应起来分析,即机电类比法分析。
