TL;DR: A design for reliability approach is proposed for fully integrated RF CMOS class A-to-C power amplifiers to reduce the full universe of available designs to those that are specification and reliability compliant, avoiding a simulator-in-the-loop approach.

Abstract: This paper introduces the concept of uplink wireless transmission technologies for visible light communication (VLC). An overview of the different uplink existing methods and its feasibility in various applications such us indoor positioning is presented. We also showed that, unlike existing technologies of wireless communication like, Bluetooth, WiFi and Zigbee, Wireless Power Transfer (WPT) can be not only used for uplink transmission but also provides energy for certain power hungry devices. Simulation results and analytical approximations show that around 450 kbps uplink throughput can be achieved in a system capable of delivering up to 1.3 mW to small indoor devices (94.6×56.8×3.65 mm).

TL;DR: This work carries out a thorough study of the advantages of using general load matching networks in two and three coil systems, showing that the efficiency is improved compared to the case of commonly used resonating structures.

TL;DR: In this paper, a split-inactivated IQB90 adjuvanted influenza vaccine triggered a strong immune response, stronger than that induced by a commercial unadjuvanted vaccine when applied either by the subcutaneous or the intranasal route.

TL;DR: A novel rail-to-rail architecture and a low-power low-voltage class AB output stage are integrated to achieve an opamp that meets the requirements of a wide range of applications.
