A charge transfer circuit for an imaging array incorporates a number of concatenated charge transfer stages. Each stage has a charge storage element for storing accumulated charge generated by a photo-detector responsive to electromagnetic radiation incident thereon, and a transfer element to which the charge storage element is coupled. A first voltage driver is coupled to the storage element and a second voltage driver coupled to the transfer element. By selectively applying respective potential conditions to the storage elements and to the transfer elements of each stage of the array the accumulated charge stored in each storage element is transferred to the storage element of the next stage of the array to provide an integrated signal at the circuit output.
