Résumé
The heart of the flat panel digital detector consists of a two-dimensional array of amorphous silicon photodiodes and thin-film transistors (TFTs), all deposited on a single substrate. We designed 4x4 matrix TFTs arrays using current mirror amplifiers. Advantages of current mirror amplifiers are they need less requiring switches and the conversion time is short. The TFT arrays 4x4 matrixes using current mirror circuits have been fabricated and tested with success. The TFT array directly can process signals coming from 16 pixels in the same node. This enables us to make the summation of the light intensities of close pixels during a reading.
