摘要
回顾了几种程控放大器的结构，给出了一种宽带高增益精密程控放大器的设计方法，该方法避免了对精密衰减器或复杂电阻网络的过高要求。
In traditional design of PGA, the user's demands was limited by the complex of the resistor network and the speed of operational amplifiers. ln this paper,we present a new method to achieve high resolution and wide band PGA, which no longer require the high reso lution attenuator or extraordinary comp1icated resistor network.
