SOI digital pixel sensor based on charge pumping

Maher Kayal, Jean-Michel Sallese, Louis Harik

In this paper, a digital pixel sensor in silicon on insulator (SOI) is presented. The active part is a partially depleted SOI phototransistor. The technique elaborated in Harik et al. (2008) [1] was designed and implemented. Moreover, we took advantage of ...

Measurement and performance evaluation of a silicon on insulator pixel matrix

Maher Kayal, Jean-Michel Sallese, Louis Harik

A new technique for driving silicon-on-insulator pixel matrixes has been proposed in [1], which was based on transient charge pumping for evacuating the extra photo-generated charges from the body of the transistor. An 8×8 pixel matrix was designed and fab ...

Pattern-Based Sensing with Metal−Dye Complexes: Sensor Arrays versus Dynamic Combinatorial Libraries

Kay Severin, Sébastien Rochat

The dyes Methyl Calcein Blue, Arsenazo I, and Xylenol Orange, and the metal salts CuCl2 and NiCl2 were used to generate colorimetric sensors for peptides. Two different approaches were followed: (1) Sensors based on dynamic combinatorial libraries of metal ...

2PFC™ Image Sensors: Better Image Quality at Lower Cost

Daniel Tamburrino

A modification to the standard Bayer CFA and photodiode structure for CMOS image sensors is proposed, which we call 2PFC™, meaning “Two Pixel, Full Color”. The blue and red filters of the Bayer pattern are replaced by magenta filters. Under each magenta fi ...

Absolute and high precision 3 degrees of freedom position sensor

Reymond Clavel, Florent Cosandier

We present a compact 3 degrees of freedom (dof) (X-Y-θz) absolute position sensor offering a sub-micrometric resolution. The travelling range is 15x15mm2 (translations) and ±180° (rotation), with an absolute precision better than 10μm over the whole travel ...
