Abstract
In this paper, we have surveyed the design procedure of CMOS LNA for Bluetooth Low Energy (BLE) and Bluetooth Technology (BT) applications. The design specifications of LNA such as noise figure, power dissipation, supply voltage, linearity, etc., have been analyzed. The design of LNA has been targeted for BLE applications range, i.e., 2.4–2.46 GHz. Bluetooth low energy is a new version of Bluetooth Technology brand, as well as it borrows plenty of practical applications from its source. Due to this, BLE should be contemplated as a brand new technology which addresses various design goals with distinct market segments. Generally, Bluetooth Low Energy (BLE) is a wireless personal area network (WPAN) technology which was marketed as well as designed by Bluetooth SIG for unique applications in the field of security, entertainment industries as well as health care. Finally, a comparison of different LNA topologies and their parameters for BT and BLE application range has been presented. The purpose of Bluetooth low energy is to provide minimum power consumption with low supply voltage and is cost-effective, with the same communication range, as Bluetooth.
