A Configurable IC to Control, Readout and Calibrate an Array of Biosensors

Giovanni De Micheli, Sandro Carrara, Seyedeh Sara Ghoreishizadeh

We present a novel integrated circuit for a biosensing data acquisition chain. The circuit controls and reads out five bimolecular sensors as well as pH and temperature sensors for biosensor calibration. The IC supports both chronoamperometry (CA) a ...

On the Exploitation of the Inherent Error Resilience of Wireless Systems under Unreliable Silicon

Andreas Peter Burg, Georgios Karakonstantis

In this paper, we investigate the impact of circuit misbehavior due to parametric variations and voltage scaling on the performance of wireless communication systems. Our study reveals the inherent error resilience of such systems and argues that sufficien ...

Nanowatt Range Folding-Interpolating ADC Using Subthreshold Source-Coupled Circuits

Yusuf Leblebici, Seyed Armin Tajalli

A very low power mixed-signal design methodology based on subthreshold source-coupled circuits is presented, and a nano-Watt range analog-to-digital converter (ADC) circuit based on folding-interpolating topology is proposed as a complete design example. T ...

Fault-Tolerance and Reliability of Post-CMOS Systems: a Circuit Perspective

Yusuf Leblebici, Alexandre Schmid, Milos Stanisavljevic

The reliability of systems made of unreliable nanoelectronic devices is discussed in this paper. Massive defect density which may affect future fabrication technologies calls for novel solutions, where spatial redundancy and the voting scheme play a signif ...

Self-Stabilizing Robot Formations over Unreliable Networks

Seth Gilbert

We describe how a set of mobile robots can arrange themselves on any specified curve on the plane in the presence of dynamic changes both in the underlying ad hoc network and in the set of participating robots. Our strategy is for the mobile robots to impl ...

Challenges in Automatic Optimization of Arithmetic Circuits

Paolo Ienne, Philip Brisk, Ajay Kumar Verma

Despite the impressive progress of logic synthesis in the past decade, finding the best architecture for a given circuit still remains an open and largely unsolved problem, especially for arithmetic circuits. In many cases, the outcome of even the most adv ...
