A 2.4-GHz low power polar transmitter for wireless body area network applications

Christian Enz, Vladimir Kopta

A 2.4 GHz low power polar transmitter is proposed in this paper. A dynamic biasing circuit, controlled by a digital envelope signal, is used as a direct digital-to-RF envelope converter. It effectively linearizes the input-output characteristic of the over ...

A sub-µA power management circuit in 0.18µm CMOS for energy harvesters

Pierre-André Farine, Cyril Botteron, Christian Robert, Gabriele Tasselli

We explore a miniature sensor node that could be placed in an environment which would interrogate, take decisions and transmit autonomously and seamlessly without the need of a battery. With the system completely powered by an energy harvester for autonomo ...

On-Chip Digital Background Calibration of Pipelined Analog-to-Digital Converters using Digital Assistance to support Nonlinear Residue Amplification

Thomas Liechti

This thesis describes a novel digital background calibration scheme for pipelined ADCs with nonlinear interstage gain. Errors caused by the nonlinear gains are corrected in real-time by adaptively post-processing the digital stage outputs. The goal of this ...

System design of a 24 GHz phased-array front-end for low-power applications

Pierre-André Farine, Cyril Botteron, Gabriele Tasselli, Ban Wang

This paper deals with the design of a 4-channel phased-array receiver Front-End (FE) architecture working at 24 GHz. Targeting low power applications such as radar sensors and medium bit-rate transceivers, a local oscillator shifting architecture is propos ...

Amplitude modulation based readout for very dense active microelectrode arrays

Yusuf Leblebici, Alexandre Schmid, Neil Joye

A readout method which is suitable for high-density active microelectrode arrays used in electrophysiology experiments is presented. Amplitude modulation of consecutive channels enables simultaneous recording and transmission of the signals recorded on mul ...

Electrical modeling and design of a wafer-level package for MEM resonators

Mihai Adrian Ionescu, Anja Skrivervik, Julien Perruisseau-Carrier, Marco Mazza

This paper presents the electrical design and characterization of a wafer-level, or 0-level, package for micro-electromechanical resonators. We start by identifying the requirements on the electrical parasitics of a packaged resonator, derived from an anal ...

Robust, High-Speed Interest Point Matching for Real-Time Applications

Michael Calonder

A typical Computer Vision system needs to process vast amounts of data as captured by one or more cameras, constantly testing the capabilities of today's hardware. Yet such systems face an ever-growing computational load caused by the more and more demandi ...
