How to solve consensus in the smallest window of synchrony

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

This paper addresses the following question: what is the minimum-sized synchronous window needed to solve consensus in an otherwise asynchronous system? In answer to this question, we present the first optimally-resilient algorithm ASAP that solves consens ...

Energy Efficiency Comparison of Asynchronous and Synchronous Circuits Operating in the Sub-Threshold Regime

Yusuf Leblebici, Omer Can Akgun

Digital circuits operating in the sub-threshold regime are able to perform minimum energy operation at a given delay. In the sub-threshold regime circuit delay, hence the leakage energy consumption depends on the supply voltage exponentially. By reducing t ...

Subthreshold Source-Coupled Logic Circuits for Ultra Low Power Applications

Seyed Armin Tajalli, Eric Vittoz, Yusuf Leblebici

This article presents a novel approach for implementing ultra-low power digital components and systems using source-coupled logic (SCL) circuit topology, operating in weak inversion (sub-threshold) regime. PMOS transistors with shorted drain-substrate cont ...

Global and local charge trapping in carbon nanotube field-effect transistors

Nicola Marzari, Ho Ling Li

The influences of trapped charges on carrier transport in carbon nanotubes (CNTs) are studied using CNT field-effect transistors with a partial top-gate and a global back-gate. Trapped charges induced by the global back-gate voltage sweeping (+/- 20 V) pro ...

Asynchronous front-end asic for x-ray medical imaging applications implemented in CMOS 0.18μm technology

Rafal Tomasz Dlugosz

An idea as well as a CMOS implementation of the novel multi-channel readout front-end ASIC for nuclear X-ray imaging system has been presented in the paper. The circuit has been designed in an example configuration with eight equal channels, but the modula ...

MOS current-mode logic standard cells for high-speed low-noise applications

Stéphane Badel

With the continuous shrinking of devices dimensions in microelectronic circuits, it is becoming extremely desirable to integrate analog circuitry together with complex digital logic blocks. The noise generated by the digital parts in a mixed-signal integra ...

Variable latency speculative addition: A new paradigm for arithmetic circuit design

Paolo Ienne, Philip Brisk, Ajay Kumar Verma

Adders are one of the key components in arithmetic circuits. Enhancing their performance can significantly improve the quality of arithmetic designs. This is the reason why the theoretical lower bounds on the delay and area of an adder have been analysed, ...

Improving the Power-Delay Product in SCL Circuits Using Source Follower Output Stage

Seyed Armin Tajalli, Yusuf Leblebici

This article explores the effect of using source follower buffers (SFB) at the output of source coupled logic (SCL) circuits. This technique can help to improve the power-delay product (PDP) in an SCL gate by a factor close to two. The proposed approach ha ...

Prospects for logic-on-a-wire

Giovanni De Micheli, Mihai Adrian Ionescu, David Atienza Alonso, Didier Bouvet, Kirsten Emilie Moselund, Yusuf Leblebici, Mohamed Haykel Ben Jamaa

In this paper we present the top-down fabrication of gate-all-around (GAA) and body-tied @W-gate devices by a combination of etching and oxidation steps resulting in a local silicon-on-insulator structure. The GAA has advantages in terms of enhanced curren ...

Non-hysteretic punchthrough impact ionization MOS (PIMOS) transistor: Application to abrupt inverter and NDR circuits

Mihai Adrian Ionescu, Kirsten Emilie Moselund, Vincent Pott

The recently proposed PIMOS transistor can offer, by appropriate operation, non-hysteretic abrupt off-on transitions due to impact ionization if the action of its parasitic bipolar transistor is minimized. This work proposes non-hysteretic abrupt inverter ...
