摘要
文中研究设计了一种基于MSP430G2553单片机控制的宽带压控放大器,它由前级固定增益放大模块、中间级压控增益放大模块、后级固定增益放大模块和衰减网络四部分组成。具有0~60d B增益可调,输出端噪声电压的峰值UoNpp≤100m V,高线性度和宽带宽等特点。
This paper designed a broadband voltage-controlled amplifier using a MSP430G2553 microcontroller as control center,the amplifier consists of four parts,including pro-fixed gain amplifier module,intermediate level gain voltage-controlled amplifier module,fixed gain amplifier module and attenuation circuit module. With the features of 0 to 60 d B variable gain,the maximum value of output noise voltage Uo Npp≤100m V,it is high linearity and wide band.
