    Abstract: A monolithic gas-sensing chip assembly for sensing a gas analyte includes a sensing material to detect the gas analyte, a sensing system including a resistor-capacitor electrical circuit, and a heating element. A sensing circuit measures an electrical response of the sensing system to an alternating electrical current applied to the sensing system at (a) one or more different frequencies, or (b) one or more different resistor-capacitor configurations of the system. One or more processors control a low detection range of the system to the gas, a high detection range of the system to the gas, a linearity of a response of the system to the gas, a dynamic range of measurements of the gas by the system, a rejection of interfering gas analytes by the system, a correction for aging or poisoning of the system, or a rejection of ambient interferences that may affect the electrical response of the system.

    Abstract: Improved imaging systems are disclosed. More particularly, the present disclosure provides for an improved image sensor assembly for an imaging system, the image sensor assembly having an integrated photodetector array and its associated data acquisition electronics fabricated on the same substrate. By integrating the electronics on the same substrate as the photodetector array, this thereby reduces fabrications costs, and reduces interconnect complexity. Since both the photodiode contacts and the associated electronics are on the same substrate/plane, this thereby substantially eliminates certain expensive/time-consuming processing techniques. Moreover, the co-location of the electronics next to or proximal to the photodetector array provides for a much finer resolution detector assembly since the interconnect bottleneck between the electronics and the photodetector array is substantially eliminated/reduced. The co-location of the electronics next to or proximal to the photodetector array also enables/facilitates programmable pixel configuration for optimal image quality.
