  • On-chip bias calibration for microbolometer detectors and readout integrated circuits
    Patent number: 11108975
    Abstract: A readout circuit that allows on-chip bias calibration of a microbolometer focal plane array (FPA). The readout circuit includes a memory for storing one or more biasing values for a plurality of pixels within the FPA, the plurality of pixels being arranged in one or more columns and one or more rows within the FPA. The readout circuit further includes a column readout connected to the memory and configured to search for the one or more biasing values and to apply a bias adjustment based on the one or more biasing values to a signal received from the FPA. The readout circuit further includes a column multiplexer connected to the column readout and configured to perform dynamic column selection for one or more columns of pixels within the FPA.
