New analogue switch circuit having very low forward resistance
(Institution of Engineering and Technology, 1984)
A new circuit realisation for an analogue switch is reported. The main feature of the proposed design is the low value of the forward resistance as compared with commercial switches. Experimental data confirming the ...

nu MOS-based sorter for arithmetic applications
(Hindawi Publishing Corporation, 2000)
The capabilities of the conceptual link between threshold gates and sorting networks are explored by implementing some arithmetic demonstrators. In particular, both an (8×8)-multiplier and a (15,4) counter which use a ...

A highly sensitive microsystem based on nanomechanical biosensors for genomics applications
(Elsevier, 2006)
Microcantilever-based biosensors are a promising tool to detect biomolecular interactions in a direct way with high accuracy. We show the development of a portable biosensor microsystem able to detect nucleic acid hybridization ...

Impact of random channel mismatch on the SNR and SFDR of time-interleaved ADCs
(Institute of Electrical and Electronics Engineers, 2004)
Using several ADCs (Analog to Digital Converters) in parallel with convenient time offsets is considered as an efficient way to push the speed limits of data acquisition systems. However, a serious drawback of this ...

Design methodology for low-jitter differential clock recovery circuits in high performance ADCs
(Springer, 2016)
This paper presents a design methodology for the simultaneous optimization of jitter and power consumption in ultra-low jitter clock recovery circuits (<100fsrms) for high-performance ADCs. The key ideas of the design ...

Testing mixed-signal cores: a practical oscillation-based test in an analog macrocell
(Institute of Electrical and Electronics Engineers, 2002)
A formal set of design decisions can aid in using oscillation-based test (OBT) for analog subsystems in SoCs. The goal is to offer designers testing options that do not have significant area overhead, performance degradation, ...

Chaos via a piecewise-linear switch ed-capacitor circuit
(Institution of Engineering and Technology, 1987)
A nonlinear switched-capacitor circuit that generates chaotic signals is reported. The circuit is described by a first-order piecewise-linear discrete equation that exhibits a chaotic dynamics. Experimental results ...

Low-cost digital detection of parametric faults in cascaded ΣΔ modulators
(Institute of Electrical and Electronics Engineers, 2009)
The test of modulators is cumbersome due to the high performance they reach. Moreover, technology scaling trends raise serious doubts on the intra-die repeatability of devices. Increase of variability will lead to ...
