Whether in medical, space or mass market imaging the consumption and utilisation of high-resolution images is endlessly increasing. Therefore it is essential to produce matrice sensors or imagers thinner than before, (pitch < 5µm), denser, (4K resolution), high dynamic range (> 12bits) and with a high speed (handreds of frames/s). The converting of millions of analog signals to a digital format whilst consuming less energy is a complex equation. MASSAR provides that solution.
A new converter architecture with successive approximation, with a reduced surface for resolutions up to 14 bits, and with a low energy consumption :
ADC Low surface (20µx1mm), respecting the width of each column of pixels
ADC Low Power (100µW for 100 Ksps/ channel)
ADC High Resolution, 12 to 14bits
Even with increased speed, energy consumption is still controlled. This control saves the high resolution performance of image sensor otherwise noise increasing with temperature leads to a significant loss of resolution.
A functional prototype demonstrator was produced and the chip validation tests are currently underway. The demonstrator was designed and produced to take into account a set of industrial loads in technology and imaging processing. Currently supported by Linksium, MASSAR will reach the end of its maturation phase in the coming months.
