Design Concepts of Low-Noise Amplifier for Radio Frequency Receivers

Abstract

The development of high-performance radio frequency (RF) transceivers or multi- standard/reconfigurable receivers requires an innovative RF front-end design to ensure the best from a good technology. In general, the performance of front-end and/or building blocks can be improved only by an increase in the supply voltage, width of the transistors or an additional stage at the output of a circuit. This leads to increase the design issues like circuit size and the power consumption. Presently, the wireless market and the need to develop efficient portable electronic systems have pushed the industry to the production of circuit designs with low-voltage power supply. The objective of this work is to introduce an innovative single-stage design structure of low noise amplifier (LNA) to achieve higher performance under low operating voltage. TSMC 0.18 micron CMOS technology scale is utilized for realizing LNA designs and the simulation process is carried out with a supply voltage of 1.8 V. The LNA performance measures are analyzed by using an Intel Core2 duo CPU E7400@2.80GHz processor with Agilent ’ s Advanced Design System (ADS) 2009 version software.
