—A fully differential variable gain amplifier (VGA) for ultra-wideband (UWB) systems has been designed in a standard 0.18μm CMOS process. The VGA is implemented using three variable gain stages followed by a fixed gain amplifier stage with a dual feedback DC-offset cancellation network to correct DC-offset. The proposed VGA shows a high linear gain range of(More)
