Equalization-Based Digital Background Calibration Technique for Pipelined ADCs
(Institute of Electrical and Electronics Engineers, 2014)
In this paper, we present a digital background calibration technique for pipelined analog-to-digital converters (ADCs). In this scheme, the capacitor mismatch, residue gain error, and amplifier nonlinearity are measured ...

A CMOS Imager for Time-of-Flight and Photon Counting Based on Single Photon Avalanche Diodes and In-Pixel Time-to-Digital Converters
(Editura Academiei Române, 2014)
The design of a CMOS image sensor based on single-photon avalanche-diode (SPAD) array with in-pixel time-to-digital converter (TDC) is presented. The architecture of the imager is thoroughly described with emphasis on the ...

Smart imaging for power-efficient extraction of Viola-Jones local descriptors
(Society of Photo-Optical Instrumentation Engineers, 2014)
In computer vision, local descriptors permit to summarize relevant visual cues through feature vectors. These vectors constitute inputs for trained classifiers which in turn enable different high-level vision tasks. While ...
