Latest Patents
One of his latest patents is an interface circuit for photodetectors that provides full-frame integration and pixel-level digitization. This photodetector interface circuit is designed to reside partially or fully within a unit cell per pixel of a focal plane array (FPA). The circuit employs an innovative approach to achieve pixel-level digitization for full-frame integration times while maintaining the use of practical-sized integration capacitors. The technique utilizes successive charge subtraction, which removes charge from an integration capacitor in a controlled manner. This process is triggered when the charge increases sufficiently to charge the integrator to a reference level. The system then triggers both charge removal and increments a count until all current flowing in the photodetector has been accounted for, resulting in a count that represents the digitization of the photodetector signal. Various arrangements for the digitization elements are also disclosed in this patent.
