  • Abstract
    A novel current differentiator capable of differentiating a step current with step size as low as 50 pA is described. It requires only four MOSFETs and consumes less than 10-8 W power. This makes the novel current differentiator, called the current-mirror (CM) differentiator, a suitable building block for the implementation of motion-detecting imagers with medium pixel density (≈60 pixels/mm2). The circuit has been implemented using 3 μm CMOS technology
