Abstract
In order to reduce the steady dark current background effect on the output sequence of charge packets in a semiconductor charge transfer device, each charge packet on its first arrival at the output end of a transfer path is inverted with respect to a suitable reference level; and the inverted charge packet is then recirculated through the same transfer path for subsequent detection on its next arrival at the output end of the path.
