Abstract
In this paper, a simple cumulative differential light-pulse detector i s presented which uses an original switched-current (SI) memory in ver y weak inversion mode. This light-pulse detector differentiates the in put lie;ht synchronously and cumulates the consecutive temporal differ ences, so a substantial detection gain can be obtained if the detectio n clock matches that of the optical signal emission. A test chip has s hown a differential sensitivity of better than 2%. The pixel density o f the image sensor is 400 pixels mm(-2) with 1.0 mm CMOS single poly t echnology.
