Design of a compact and low-power TDC for an array of SiPM's in 110nm CIS technology
(Institute of Electrical and Electronics Engineers, 2017)
Silicon photomultipliers (SiPMs) are meant to substitute photomultiplier tubes in high-energy physics detectors and nuclear medicine. This is because of their -to name a few interesting properties- compactness, lower bias ...

Geometrically-constrained, parasitic-aware synthesis of analog ICs
(The International Society for Optical Engineering - SPIE, 2005)
In order to speed up the design process of analog ICs, iterations between different design stages should be avoided as much as possible. More specifically, spins between electrical and physical synthesis should be reduced ...

A Tool for automated design of sigma-delta modulators using statistical optimization
(Institute of Electrical and Electronics Engineers, 1993)
A tool is presented which starting from high level specifications of SC σδ modulators (resolution, bandwidth and oversampling ratio) calculates first optimum specifications for the building blocks (op-amps, comparator, ...

A 0.18 μm CMOS low noise, highly linear continuous-time seventh-order elliptic low-pass filter
(The International Society for Optical Engineering- SPIE, 2005)
This paper presents a fast procedure for the system-level evaluation of noise and distortion in continuous-time integrated filters. The presented approach is based on Volterra's series theory and matrix algebra manipulation. ...

Design Considerations for an Automotive Sensor Interface Sigma-Delta Modulator
(Institute of Electrical and Electronics Engineers, 2003)
The Sigma-Delta Modulator presented in this paper contains a programmable-gain input inferface to accommodate the output signal level of a variety of automotive sensors. We show that this characteristic can be efficiently ...

On the design of a sparsifying dictionary for compressive image feature extraction
(Institute of Electrical and Electronics Engineers, 2015)
Compressive sensing is an alternative to Nyquist-rate sampling when the signal to be acquired is known to be sparse or compressible. A sparse signal has a small number of nonzero components compared to its total length. ...

A multiplexed mixed-signal fuzzy architecture
(Institute of Electrical and Electronics Engineers, 1998)
Analog circuits provide better area/power efficiency than their digital counterparts for low-medium precision requirements. This limit in precision as well as the lack of design tools when compared to the digital approach, ...

Hysteresis based neural oscillators for VLSI implementations
(Institute of Electrical and Electronics Engineers, 1991)
The actual tendency in most of the work that is being done in VLSI neural network research is to use the simplest possible models to perform the desired tasks. This yields to the use of sigmoidal type neurons that have ...

Real-time single-exposure ROI-driven HDR adaptation based on focal-plane reconfiguration
(Society of Photo-Optical Instrumentation Engineers, 2015)
This paper describes a prototype smart imager capable of adjusting the photo-integration time of multiple regions of interest concurrently, automatically and asynchronously with a single exposure period. The operation is ...

A CNN-driven locally adaptive CMOS image sensor
(Institute of Electrical and Electronics Engineers, 2004)
A bioinspired model for mixed-signal array mimics the way in which images are processed in the visual pathway. Focal-plane processing of images permits local adaptation of photoreceptor structures in silicon. Beyond simple ...
