    Abstract: In this paper, an ultra-low-power low-noise amplifier (LNA) at 5GHz is proposed. The main focus is on precise computation of output impedance, input impedance, and gain of the LNA. The LNA is composed of a common-source LNA and a cascode LNA. In fact, the casode LNA can assist to have more stability by declining S12 considerably. Plus, it can be be... Show More

    Abstract: Spectral efficiency (SE) and energy efficiency (EE) play major roles in evaluating the quality of service (QoS) of a wireless communication system. Designing an efficient wireless communication system requires trade-off between these two parameters. Orthogonal frequency division multiplexing technique with Index Modulation (OFDM-IM) has been introduce... Show More
