摘　　要：本文介绍了一款基于AD8065和TH4052两个运算放大器来实现多个放大倍数的宽带前置放大电路,可以对1伏或5伏的大信号(带宽不低于DC～10MHZ)进行一定倍数的放大或衰减,在一定带宽范围内,放大或衰减小信号,对于信号的放大或衰减的倍数可以方便调节。设计新颖,方便实用。This artical mainly introduces a type of wideband preamplifier circuit to implement multiple magnification with two operational amplifiers based on AD8065 and TH4052, which can conduct amplification and attenuation for the 1V or 5V large signal （ with the bandwidth not lower to DC-10MHZ） within certain multiples. With such range of bandwidth to amplify or attenuat the signal, it is quite convenient to regulate the multiples of signal amplification and attenuation with the quality of novel design and practical function.
