Abstract :
We present the design and experimental measurements of an integrate-and-fire pixel for address-event-representation (AER) transceiver chips such that (a) input events can be weighted according to a digital word, (b) this weight includes a sign bit, (c) the incoming event is accompanied by a sign bit, and (d) the pixel can be calibrated to compensate for mismatch in large arrays of these pixels. A prototype has been fabricated in the AMS 0.35 μm CMOS process, whose experimental measurement results are provided.
