Due to the advantages of the uncooled infrared focal plane array (UIFPA), it is widely used in various fields. To achieve more vivid image, the dimensions of infrared focal plane array need to be enlarged. Hence the high speed analog to digital converter (ADC) integrated on-chip needs to obtain the digital infrared imaging signal. We propose a new single slope ADC with half-period counter and two ramp generators to realize the high resolution digitizing, which can operate at much lower speed. The operation speed of this proposed single slope ADC can be decreased to the 25% of the conventional structure while the static characteristics are still good.
