摘要： MOS imaging pixels are described. The MOS imaging pixels may comprise bootstrapped source followers, having their bodies connected to their sources. The source followers of the MOS imaging pixels may be used to buffer a signal indicative of an amount of radiation incident on the pixel. MOS imagers are also described, which may comprise one or more MOS imaging pixels of the type described.

摘要： Optical imaging structures and methods are disclosed. One structure may be implemented as an imaging pixel having multiple photodetectors. The photodetectors may detect different wavelengths of incident radiation, and may be operated simultaneously or at separate times. An imager may include an imaging array of pixels of the type described. Methods of operating such structures are also described.

摘要： Imagers, pixels, and methods of using the same are disclosed for imaging in various spectra, such as visible, near infrared (IR), and short wavelength IR (SWIR). The imager may have an imaging array having pixels of different types. The different types of pixels may detect different ranges of wavelengths in the IR, or the SWIR, spectra. The pixels may include a filter which blocks some wavelengths of radiation in the IR spectrum while passing other wavelengths. The filter may be formed of a semiconductor material, and therefore may be easily integrated with a CMOS pixel using conventional CMOS processing techniques.

摘要： Methods and apparatus are provided for performing multiple correlated double sampling (CDS) operations on an imaging pixel, and in some cases on an array of imaging pixels, during a single integration cycle of the pixel(s). The multiple CDS operations may produce multiple CDS values, which may be processed in combination to produce a resulting value substantially free of various types of noise. The CDS operations may be performed using a CDS circuit including a single-ended charge amplifier having an input capacitor. The charge amplifier may also include a variable capacitance providing a variable gain. The variable capacitance may be provided by a feedback capacitor.

摘要： Imaging arrays comprising at least two different imaging pixel types are described. The different imaging pixel types may differ in their light sensitivities and/or light saturation levels. Methods of processing the output signals of the imaging arrays are also described, and may produce images having a greater dynamic range than would result from an imaging array comprising only one of the at least two different imaging pixel types.
