Abstract
A 120dB dynamic range 2times256 dual-line optical transient sensor uses pixels that respond asynchronously to relative intensity changes. A time stamp with variable resolution down to 100ns is allocated to the events at the pixel level. The pixel address and time stamp are read out via a 3-stage pipelined synchronous arbiter. The chip is fabricated in 0.35mum CMOS, runs at 40MHz and consumes 250mW at 3.3V
