A 90nm Low Noise Amplifier Using Active Inductor for Ultra Wideband Application

This paper presents a LNA for UWB radio receiver at 2 to 6GHz victimization 0.09µm TSMC Technology wherever 009µm technology is for lower power consumption. UWB radio that created up in between the frequency vary of 2GHz to 6GHz.The basic design of LNA includes a RF electronic equipment within the middle of input matching network and also the output matching network. We’ve designed a LNA that consist low noise figure, good input and output resistivity matching and high gain and stability LNA, wherever operative temperature is 27 ºC gain is 20dB and would have smart stability. we have a tendency to used ltspice tool for the simplest performance and accuracy for results, this work represents associate LNA schematic compose of Common source LNA and Cascode LNA, wherever Common source LNA is employed for glorious input and output matching and also the cascode LNA for low Noise figure and high gain, an extra feature is that single terminated LNA employs inductive supply degeneration conception (inductor Ls is connected to the supply of semiconductor device M1) wherever M1 contains a larger management over the worth of the important a part of the input impedance through the selection of the inductance. Cascode semiconductor device power supply is employed to scale back the interaction of the tuned output with the tuned input.
