The present invention is directed to an improved CCD utilizing a potential gradient along the lengths of the various channels of the CCD during charge transfer to cause generated electrical charge to migrate along the length of the channel to a summing well. The potential gradient is formed by biasing the opposing ends of the electrodes overlying the lengths of the various channels with different voltages.

Large cell charge coupled device for spectroscopy

The present invention is directed to a charge coupled device in which, during the shifting interval, the charge storage pixels are biased with an electrical potential greater than the absolute value of the CCD inversion potential and, during the charge integration interval, the charge storage pixels are biased with an electrical potential that is less than the CCD inversion potential. In this manner, the present invention substantially reduces error attributable to impact ionization or dark current.

Phase clock drive circuit and method for reduction of readout noise in

A system for power coupling independent of the position of the receiver over a surface. This is achieved by developing a spatially-dependent phase shift in the electromagnetic field generated by the power transmitter. The power inputs to the power receiver are then driven 180 degrees out of phase at any coordinate in the plane over the surface. An array of elements is placed in a plane below a surface and driven with a series of alternating current power sources. Consecutive adjacent elements across the area of the plane are driven with uniformly increasing phase shift. An integral multiple of adjacent consecutive elements results in a 180 degree phase shift. Pairs of field receiving elements in a power receiver are dimensioned to receive fields that are separated by 180 degrees of phase. Utilizing the technique of the invention, power coupling independent of the position or rotational orientation of the power receiver can be obtained.
