Abstract

The most important challenges in Ultra Wideband Low Noise Amplifiers (LNAs) are flatness of gain, input impedance matching and lower noise figure at desired frequencies. In this paper, an Ultra Wideband Low Noise Amplifier with Flat Gain and Low Noise Figure at frequencies between 3. 1GHz to 10. 6 GHz is proposed. In the proposed circuit, a cascade stage is used as a main block and Noise Cancellation method is used for increasing gain and lowering noise figure. To have good input and output matching, active feedback is used. In addition feedback and RLC load is used for better flatness for gain of LNA. The proposed circuit is designed and simulated in TSMC 90nm CMOS Technology using HSpice simulator. Simulations show noise figure of 1. 62-2. 1dB, Flat Gain in the range of 11. 9-12dB and power consumption of 11. 72mW in the frequency range of 3. 1-10. 6GHz.
