Indirect X-ray photon counting imager for color medical radiology

Offer N°: SL-DRT-15-0614

Start date: 1 Sep 2015

As part of its activities in medical imaging, Leti has developed over several years several detectors technology, in order to propose new performance in X-ray imaging for different applications like radiology and X-ray CT scanner, gamma-camera, and for non-destructive testing. The first prototypes have shown a great interest in improving the image quality and dose reduction.


Low temperature Electron-beam-induced current (EBIC) characterization of 3rd gen IR detectors

Offer N°: SL-DRT-15-0605

Start date: 1 Oct 2015

The optronic departement of LETI (DOPT) is a key laboratory in the field of high performance quantum IR imaging. We work in close collaboration with Sofradir, today a world leader manufacturer of high performance IR focal plane arrays. The increasing complexity of those IR retina (megapixel formats, ultra-fine pixel pitches, multicolor detection, and high operating temperature) calls for new advanced characterization methods.


Adequate approximate computing for high energy-efficiency in Internet of Things applications

Offer N°: SL-DRT-15-0320

Start date: 1 Sep 2015

Approximate and inexact computing are non-conventional paradigms that allow bounded errors in calculation to obtain significant benefits in energy, performance, or circuit area [1]. The thesis will bring these paradigms one step further, to adequately-approximate computing, by investigating dynamic accuracy adaptation. The candidate will propose methods to control hardware inexactness in software, in order to just meet the accuracy demands of applications, under strong energy constraints.


STT-MRAM cell integration and study for high speed and ultra-low power consumption

Offer N°: SL-DRT-15-0705

Start date: 1 Sep 2014

To overcome the limitations in terms of current consumption and miniaturization logic circuits, the semiconductor industry incorporates more components of non-volatile memories within those chips. Among them, the STT-MRAM magnetic memories are the most promising. The attractiveness of this innovative technology comes with its very high programming speed (GHz) and its infinite endurance.
