Latest Patents
One of Hall's latest patents is for a "Floating gate amplifier using conductive coupling for charge coupled." This invention allows for non-destructive readout in CCDs by utilizing a floating gate that is conductively coupled through a high resistance element to a bias voltage. The design features a lower level of metallization embedded in an insulating layer, which crosses the charge transfer channel. In one embodiment, the floating gate connects to the source of a metal-oxide-semiconductor transistor, while in another, a diode is used to enhance the functionality. This innovation improves sensitivity by transferring charge packets through control gates adjacent to the floating gate.
Another significant patent is the "Block output CCD imager." This invention features an output shift register with a number of bits that is a multiple of the number of columns of pixels in the imager. The design allows for non-destructive, simultaneous readout of multiple bits, which can be pre-processed or displayed without needing to store each bit in computer memory. This advancement streamlines the imaging process and enhances performance.
