Abstract
A demodulation sensor () is described for detecting and demodulating a modulated radiation field impinging on a substrate (). The sensor comprises the means () for generating, in the substrate, a static majority current assisted drift (Edrift) field, at least one gate structure () for collecting and accumulating minority carriers (), the minority carriers generated in the substrate by the impinging radiation () field. The at least one gate structure comprises at least two regions () for the collection and accumulation of the minority carriers () and at least one gate () adapted for inducing a lateral electric drift field under the gate structure, the system thus being adapted for directing the minority carriers () towards one of the at least two regions () under influence of the static majority current assisted drift field and the lateral electric drift field induced by the at least one gate, and a means for reading out the accumulated minority carriers in that region.
