ABSTRACT:
A CMOS imaging device which includes a charge pump connected to one or more of a reset gate, transfer gate and row select gate of sensor cells and provides gate control signals which give the imaging device an increased dynamic range charge capacity while minimizing signal leakage. A charge pump may also supply control signals to photogates used in the cells.
