摘要：This paper presents a Low Noise Amplifier for UWB Radio Receiver at 8.72GHz using 0.18μm UMCTechnology where 0.18μm technology is for lower power consumption. UWB Radio Receiver which made up in betweenthe frequency range of 3.1GHz to 10.6GHz.The basic architecture of LNA comprises a RF amplifier in the middle of inputmatching network and the output matching network. We have designed a low noise amplifier that consist low noise figure,good input and output impedance matching and high gain and stability that exhibits the properties of standard MAX-2640LNA, where operating temperature is 27 ºC gain is 20dB and would have good stability. We used cadence tool for the bestperformance and accuracy for results, this work represents an LNA schematic compose of Common gate LNA and CascodeLNA, where Common gate LNA is used for excellent input and output matching and the cascode LNA for low Noise figureand high gain, an additional feature is that single ended LNA employs inductive source degeneration concept (inductor Ls isconnected to the source of transistor M1) where M1 has a greater control over the value of the real part of the inputimpedance through the choice of the inductance. Cascode transistor M2 is used to reduce the interaction of the tuned outputwith the tuned input and M2 is used to reduce the interaction of the tuned output with the tuned input
