FM-UWB: Towards a Robust, Low-Power Radio for Body Area Networks

Christian Enz, Vladimir Kopta

The Frequency Modulated Ultra-Wideband (FM-UWB) is known as a low-power, low-complexity modulation scheme targeting low to moderate data rates in applications such as wireless body area networks. In this paper, a thorough review of all FM-UWB receivers and ...

Optimization of the Data Rate of an OOK CMOS Medical Transmitter Based on LC Oscillators

Catherine Dehollain, Franco Maloberti, Kerim Türe, Gürkan Yilmaz

This paper presents techniques for increasing communication data rates for OOK modulated signals in the case the carrier frequency is generated by a cross-coupled pair LC oscillator. The proposed circuitry completely turns off the transmitter during the tr ...

A Time-Division Multiplexing Signaling Scheme for Low-Power Multi-Drop Memory Links

Chen Cao, Yusuf Leblebici, Gain Kim, Kiarash Gharibdoust

A time-division multiplexing (TDM) digital channel coding scheme for wireline multi-drop interfaces has been proposed. Shaping the TX spectrum to avoid channel frequency notches, the proposed digital TDM signaling reduces inter-symbol interference (ISI) an ...

Cross-Layer Energy-Efficiency Optimization of Packet Based Wireless MIMO Communication Systems

Andreas Peter Burg, Georgios Karakonstantis, Carl Christian Sten Dominic Senning

Energy in today's short-range wireless communication is mostly spent on the analog-and digital hardware rather than on radiated power. Hence, purely information-theoretic considerations fail to achieve the lowest energy per information bit and the optimiza ...

Ultra Low-Power Frequency Synthesizers for Duty Cycled IoT radios

Raghavasimhan Thirunarayanan

Internet of Things (IoT), which is one of the main talking points in the electronics industry today, consists of a number of highly miniaturized sensors and actuators which sense the physical environment around us and communicate that information to a cent ...

A compressed beamforming framework for ultrafast ultrasound imaging

Jean-Philippe Thiran, Yves Wiaux, Rafael Eduardo Carrillo Rangel, Olivier Bernard, Adrien Georges Jean Besson, Dimitris Perdios, Marcel Arditi

Classical beamforming methods, based on Delay- And-Sum (DAS) require an extensive number of samples and delay calculations to obtain high-quality images. Compressed Beamforming (CB) proposes an alternative to DAS, based on compressed sensing, which aims at ...

iPRP - the Parallel Redundancy Protocol for IP Networks: Protocol Design and Operation

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Maaz Mashood Mohiuddin, Miroslav Popovic

Reliable packet delivery within stringent delay-constraints is of paramount importance to mission-critical computer applications with hard real-time constraints. Because retransmission and coding techniques counteract the delay requirements, reliability ma ...

A 420 mu W, 4 GHz Approximate Zero IF FM-UWB Receiver for Short-Range Communications

Christian Enz, Vladimir Kopta

A low-power FM-UWB receiver intended for short range communications in wireless sensor networks is presented in this paper. It utilizes an "approximate zero IF" architecture which combines a free-running ring oscillator as the RF LO with a modified delay-l ...

Analog Programmable Distance Calculation Circuit for Winner Takes All Neural Network Realized in the CMOS Technology

Rafal Tomasz Dlugosz

This paper presents a programmable analog current-mode circuit used to calculate the distance between two vectors of currents, following two distance measures. The Euclidean (L2) distance is commonly used. However, in many situations, it can be replaced wi ...
