Ramsey-mode Rb cell clock demonstration with a 3D-printed microwave cavity

We demonstrate operation of a Ramey-mode Rb vapor-cell atomic clock based on a microwave cavity realized by additive manufacturing (3D-printing). The cavity design is based on a loop-gap approach and its critical electrode structure is realized in one mono ...

Automated Integration of Dual-Edge Clocking for Low-Power Operation in Nanometer Nodes

Andreas Peter Burg, Adam Shmuel Teman, Andrea Bonetti, Nicholas Alexander Preyss

Clocking power, including both clock distribution and registers, has long been one of the primary factors in the total power consumption of many digital systems. One straightforward approach to reduce this power consumption is to apply dual-edge-triggered ...

PolarBear: A 28-nm FD-SOI ASIC for Decoding of Polar Codes

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Thomas Christoph Müller, Andrea Bonetti, Pascal Giard

Polar codes are a recently proposed class of block codes that provably achieve the capacity of various communication channels. They received a lot of attention as they can do so with low-complexity encoding and decoding algorithms, and they have an explici ...

A new promoter element associated with daily time keeping in Drosophila

Felix Naef, Eric Paquet

Circadian clocks are autonomous daily timekeeping mechanisms that allow organisms to adapt to environmental rhythms as well as temporally organize biological functions. Clock-controlled timekeeping involves extensive regulation of rhythmic gene expression. ...

Systems Chronobiology: Global Analysis of Gene Regulation in a 24-Hour Periodic World

Felix Naef, Jake Yeung, Jérôme Mermet

Mammals have evolved an internal timing system, the circadian clock, which synchronizes physiology and behavior to the daily light and dark cycles of the Earth. The master clock, located in the suprachiasmatic nucleus (SCN) of the brain, takes fluctuating ...

A 4×9 Gb/s 1 pJ/b Hybrid NRZ/Multi-Tone I/O with Crosstalk and ISI Reduction for Dense Interconnects

Seyed Armin Tajalli, Yusuf Leblebici, Kiarash Gharibdoust

A low-power 4-channel hybrid NRZ/multi-tone transceiver for multi-drop bus (MDB) memory interfaces is designed and fabricated in 40 nm CMOS technology. The proposed system achieves 1 pJ/bit power efficiency, while communicating over an MDB channel with 45 ...

Ultrasonic driving method

Jacques Jacot

A method for driving a first component (11) into a second component (12) by superimposing a mechanical wave of ultrasonic frequency (18) onto the movement (17) of at least one of the components (11, 12). The method comprises a step of adjusting the paramet ...

Cyber-attack on Packet-Based Time Synchronization Protocols: the Undetectable Delay Box

Jean-Yves Le Boudec, Aswin Suresh, Sergio Barreto Andrade

We present a cyber-attack on packet-based time synchronization protocols (PBTSP) with high-accuracy requirements. The cyber-attack is undetectable from the PBTSP's perspective and exploits a vulnerability that is in the nature of all PBTSPs. It can be succ ...

Timing by rhythms: Daily clocks and developmental rulers

Andrew Charles Oates

Biological rhythms are widespread, allowing organisms to temporally organize their behavior and metabolism in advantageous ways. Such proper timing of molecular and cellular events is critical to their development and health. This is best understood in the ...
