摘要：

A　novel　digital　programmable　gain　amplifier　(PGA)　is　proposed　in　this　paper.　The　proposed　design　avoids　the　gain　accuracy　affected　by　on-resistance　of　control　switches,　leading　to　much　more　accurate　gain.　The　cor-responding　algorithm　is　shown　in　this　paper.　The　circuits　are　implemented　in　CSMC　0.35　μm　Technology.　When　the　gain　is　from　0dB　to　20dB,　step　is　2dB;　from　0dB　to　-20dB,　step　is　20dB.　It　is　concluded　that　the　difference　of　the　gain　between　simulation　result　and　theoretical　value　is　within　±0.05　dB.　©　2014　IEEE.
