Past Results, Present Trends, and Future Challenges in Intrabody Communication

Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018
Intrabody communication (IBC) is a wireless communication technology using the human body to develop body area networks (BANs) for remote and ubiquitous monitoring. IBC uses living tissues as a transmission medium, achieving power‐saving and miniaturized transceivers, making communications more robust against external interference and attacks on the ...

Push–pull mode digital control for LLC series resonant dc‐to‐dc converters

IET Power Electronics, Volume 8, Issue 11, Page 2115-2124, November 2015., 2015
This study presents the design and performance evaluation of the digital control adapted to an LLC series resonant dc‐to‐dc converter operating with wide input and load variations. The proposed control design correctly incorporates the wide‐varying power stage dynamics and variable small‐signal gain of a digitally controlled oscillator, thereby ...

Design of an All‐Digital Synchronized Frequency Multiplier Based on a Dual‐Loop (D/FLL) Architecture

VLSI Design, Volume 2012, Issue 1, 2012., 2012
This paper presents a new architecture for a synchronized frequency multiplier circuit. The proposed architecture is an all‐digital dual‐loop delay‐ and frequency‐locked loops circuit, which has several advantages, namely, it does not have the jitter accumulation issue that is normally encountered in PLL and can be adapted easily for different FPGA ...

RGB‐Single‐Chip OLEDs for High‐Speed Visible‐Light Communication by Wavelength‐Division Multiplexing

Advanced Science, Volume 11, Issue 47, December 18, 2024.
High‐speed red, green, and blue organic light‐emitting diodes (RGB‐OLEDs) are integrated onto a single substrate and achieve a record data transmission rate for an OLED transmitter system of 3.2 Gbps by exploiting wavelength‐division multiplexing. It is demonstrated that integrating RGB pixels is a useful way to increase the data transmission rate of ...

Semidigital PLL Design for Low‐Cost Low‐Power Clock Generation

Journal of Electrical and Computer Engineering, Volume 2011, Issue 1, 2011., 2011
This paper describes recent semidigital architectures of the phase‐locked loop (PLL) systems for low‐cost low‐power clock generation. With the absence of the time‐to‐digital converter (TDC), the semi‐digital PLL (SDPLL) enables low‐power linear phase detection and does not necessarily require advanced CMOS technology while maintaining a technology ...

The Effect of Intermittent Signal on the Performance of Code Tracking Loop in GNSS Receivers

Journal of Electrical and Computer Engineering, Volume 2011, Issue 1, 2011., 2011
This paper analyzes the code tracking performance in the presence of signal blanking in Global Navigation Satellite System (GNSS). The blanking effect is usually caused by buildings that obscure the signal in either a periodic or random manner. In some cases, ideal blanking is used to remove random or periodic interference.
