Appl. No.:

13/615987
Inventors:

Kenneth R. Salvestrini - Tucson AZ, US
Zhenwu Wang - Moorpark CA, US
Hailing Guan - Oak Park CA, US
David Dozor - Tucson AZ, US
Assignee:

Infrared Laboratories, Inc. - Tucson AZ
International Classification:

H04N 5/378
US Classification:

25033902, 2502081
Abstract:

Readout integrated circuits (ROICs) for multi-band imagers, and related methods, are described. The ROICs may include multiple channels associated with the detectors of a photodetector array, with the different channels corresponding to different wavelength bands detected by the detectors. The ROICs may utilize capacitive transimpedance amplifier (CTIA) technology, and may implement time division multiplexing techniques.

Appl. No.:

13/618622
Inventors:

Kenneth R. Salvestrini - Tucson AZ, US
Hailing Guan - Oak Park CA, US
Zhenwu Wang - Moorpark CA, US
David Dozor - Tucson AZ, US
Assignee:

Infrared Laboratories, Inc. - Tucson AZ
International Classification:

H04N 5/378
US Classification:

2502081
Abstract:

The present application relates to imagers having variable gain and related structures and methods. The gain of the imager may vary between rows of the imager. Such variability may be achieved by suitable design of a readout integrated circuit (ROIC). The ROIC may provide different integration period durations for different rows of the imager. Different integration capacitances may be provided for pixels of different rows of the imager. The gain of a column buffer may be varied when operating on output signals of pixels from different rows.
