| Abstract: | 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. |
