A review of LNA topologies for wireless applications

This paper presents the reviews of few previous works for low noise amplifier design (LNA). This paper will explore several recent architectures of LNA but focused on four techniques of topologies which are forward body bias, self-biased inverter, common source cascade and cascode technique. Those architectures are able to minimize power consumed in a typical CMOS for wireless sensor network (WSN). Besides, high gain, low noise, input and output matching are also reviewed. As to provide extremely low power and also optimized all characteristics aspects, the performance for each topologies then are discussed. Further research will be conducted based on these four topologies comparisons in order to design a new successful LNA.
