This paper explore the Off-on Cycle ADC (OOC ADC), an innovative analog-to-digital conversion (ADC) technique that significantly simplifies the analog-to-digital conversion process by accomplishing it through just three steps: inputting the analog signal, triggering the probe’s dip-and-reset motion (PDR), and outputting the binary digital signal. Initially, the paper establishes a theoretical foundation for subsequent ADC design by introducing the Off-on Cycle principle (OOC principle) in binary encoding rules. Subsequently, it illustrates the design concepts and operational principles of the OOC ADC through the illustrative example of a 4-bit precision OOC ADC design. Finally, the paper compares the superior performance of the OOC ADC over existing ADCs in terms of conversion rate, resolution, process complexity, and power consumption. The research findings in this paper have the potential to drastically reduce the technical difficulties involved in analog-to-digital conversion, facilitate technological advancements in the realm of digital signal processing.
