چکیده
This paper proposes a high gain and wide bandwidth amplifiers with numerical approach. It is improved that the low-frequency characteristics and the range of gain refers to direct-coupling. The gain is controlled with numerical approach,which makes the gain stability. It is easy to control the gain of the multistage amplifier with adopting uniform gain control voltage. It is useful for numerical approach because of the linear between control voltage and the gain. AVR microcontroller is the heart of numerical unit. The gain is been preset and adjusted through keyboard. Most of index can be showed through LCD. NC linkage switching technology is used to switch between two or three multistage amplifier,it is useful to enabling a more flexible application of the amplifier.

A New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
