Abstract
A charge coupled device (CCD) includes a low noise charge gain circuit that amplifies charge of a cell dependent upon the charge accumulated by the cell. The low noise charge gain circuit receives clocking signals, such as from an input diode, which allow charge to accumulate in a reservoir well and then flow into a receiving well. The low noise charge gain circuit also receives a voltage signal corresponding to charge accumulated on an associated cell. The amount of charge flowing into the receiving well depends on this voltage signal.
