Simplifying complex digital sequential circuit by an innovative mixed-signal circuit alternative

This research paper presents an innovative circuit design of a Next Clock Auto-Generator (NCA). A sequential analog circuit designed to produce a digital pulse for triggering digital components using the innovative Auto-Sensing Mechanism (ASM). The NCA is notable for its minimalistic design, employing only a basic set of resistors and a capacitor. Furthermore, it offers seamless integration with analog sensor modules, leveraging a transition from high to low voltage to generate the triggering pulse. The careful selection of resistor and capacitor values facilitates the conversion of this analog signal into a digital format while providing precise control over the duty cycle (DC). In addition to its primary function as a digital pulse generator, the NCA module can serve as a sequential trigger for a wide range of digital components. In this proposed system, a 20kΩ resistor and a 10 pF capacitor incorporate NCA's active high signal of 12 ns, which corresponds to a DC of 12 %. The resistor changes to 10kΩ in the NCA results in a shortened active high to 5 ns, representing a DC of 5 %. This versatile and compact circuit design holds great promise for very large scale integration (VLSI) applications.
