摘要：

In　this　paper,　a　dual　gain　control　(DGC)　technology　is　proposed　to　achieve　large　gain　variation　range　and　good　gain　flatness　for　every　controllable　gain　in　ultra　wide　frequency　band.　The　DGC　technology　includes　a　modified　current　mirror　structure　and　a　dynamic　signal　feedback　structure.　Based　on　the　DGC　technology,　a　variable　gain　amplifier　with　both　large　dynamic　gain　variable　range　and　good　gain　flatness　in　the　ultrawideband　of　3.1∼10.6　GHz　are　realized.　©　2016　IEEE.
