Active Pixel Sensors used in High Energy Particle Physics require low power consumption to reduce the detector material budget, integration time possibilities of pile-up and fast readout improve data capability. To satisfy these requirements, a novel Address-Encoder Reset-Decoder (AERD) asynchronous circuit for pixel matrix has been developed. The AERD data-driven architecture operates address encoding reset decoding based on an arbitration tree, allows us only hit pixels. Compared...
