ABSTRACT:
A method and apparatus for propagating charge through a time division and integration (TDI) sensor is provided. The method and apparatus may be used with the TDI sensor to inspect specimens, the TDI sensor operating to advance an accumulated charge between gates of the TDI sensor. The design comprises controlling voltage waveform shapes for waveforms advancing the accumulated charge between gates in a substantially nonsquare waveform, such as a composite, sinusoidal, or other shaped waveform. Controlling voltage waveform shapes operates at different voltage phases in adjacent gates to provide a substantially de minimis net voltage.
