Pyxalis custom offer


Through dedicated IP portfolio and know how, Pyxalis can offer its partners a key technology differentiation to enable success :

_DSF3009-W250Very High dynamic range

Pyxalis can offer an innovative dynamic range (patented) that allows in a single frame readout to get a programmable wide dynamic range up to 120dB. Furthermore, this approach allows a linear response well suited for color applications (true color) and a minimum of processing off chip (no calibration)



digImage processing and Smart sensors

Pre-processing is important in many markets to ease application or reduce system processing overheads. Pyxalis ‘s experience allows to integrate on-chip a wide range of interesting functions such as a highly programmable multi-Regions Of Interest (ROI) including single or multiple integrations features , frame statistics, or a host of other digital functions. Pyxalis has the know-how to embed image processing through a compact & high performing 32bits microprocessor core.


_DSF5279-W250Global shutter pixel and High Speed Imaging

The Global shutter is an important feature for fast moving object imaging for application particularly in the industrial markets. A unique high performing global shutter is part of Pyxalis technology portfolio. Through optimized architecture combined with a column AD converter (up to 14 bits), a very high frame rate can be achieved with high image quality.


_DSF3002-W250Low light Imaging

Pyxalis experience covers the design of sensors to optimize the image capture in darkness or in the NIR.




_DSF3032-W250Large sensors : Up to one die per 12″ wafer

Specific applications for example in medical or non destructive testing require very large area image arrays. The Pyxalis team has worked on several technologies using 1D or 2D stitching techniques including post process. Dedicated optimization has been implemented to make the sensor robust in terms of yield and reliability (ESD & latch up).


Semi-Custom Sensors

On top of its Full Custom Sensors and Design Services, Pyxalis offers now semi-custom Sensors. Pyxalis is developping  his own platform products for specific application domains and those plateform sensors can be customized on demand. Pyxalis is particulary proud to announce the release of his first platform: HDPYX.

The HDPYX sensor is a 3MP, 120dB linear Dynamic range sensor, dedicated to metrolog,  Scientific imaging, high end security… . it features a flexible shutter operation (Rolling, Global, Global low noise) using an HDR 10um pixel and dedicated patented sensor architecture. The Sensor embeds two High Dynamic range methods to reach 120dB Dynamic range. The sensor is also capable of acquiring low light levels with a noise floor measured at 2,6e- RMS.


It can be extensively customized depending on your application:

  • • Modified EPI thickness for NIR operation_DSF3010-W250
  • • Back Side Illumination
  • • UV enhancement
  • • Specific custom color filters
  • • Custom Color Filters
  • • Custom packaging
  • • …

…Or it can be used as is for many different applications.

CreaPYX: a unique Pixel Evaluation platform

CreaPYX concept

creapyx_logoIn image sensor business, the pixel is the key component that can make the difference between the success and the failure of a particular product. Design house tend to prototype pixels on test runs, or shuttle runs, prior to developing a complete product. The idea behind CreaPYX platform is to shorten the prototyping cycle time as much as possible so design house can focus on what matters: make the best pixel possible and test it as fast as possible!

Pyxalis offers to Design houses a complete solution for prototyping pixels comprising:

  • A customized, fully silicon proven Pixel-frame layout, to the required dimensions, in the target technology:


  • A test system fully compatible with the Pixel frame.



A flexible platform

Different market require different pixels and CreaPYX platform can serve most of the needs you may have in terms of pixels designs:

• 3T, 4T, 5T, NT architecturescore
• Pixel pitch from 1um to 500 um
• Shared or non-shared pixels 
• Time-gating pixels
• Anti-blooming pixels
• Negative pixel biasing
• TDI operation
• NMOS/PMOS pixel types
• Local CCD
• Front Side Illumination / Back Side Illumination
• Tunable multiple voltage, Rise and fall time of pixel control lines.


A proven test environment

CreaPYX testing platform provides a simple, fast and proven testing environment to evaluate pixels designed in the CreaPYX frame. Based on USB 3, it makes it possible to the the impact of timing modification, supply voltage variation and biasing condition in real time! If you do not wish to use the provided environnement, Pyxalis provides DLLs to integrate the CreaPYX platform in Matlab or Labview environment.
