Amidst rapid advancements in the realm of computer science, integrated circuits emerge as pivotal to technological progression, influencing a diverse range of sectors significantly. This study delves into a 4-bit absolute-value detector, a crucial tool in signal detection, which evaluates the magnitude of a given inputs absolute value against a predetermined threshold and conveys the outcome. The paper presents an innovative, optimized design for a 4-bit absolute-value detector, employing CMOS technology. A novel, efficient 3-bit adder is developed and incorporated in the circuit to minimize gate delay and energy usage. By fine-tuning the applied voltage (Vdd) and implementing gate sizing, the delay is maintained at approximately 1.5 times the minimum possible delay, while ensuring low power consumption. The defined parameters for this detector are 145.05 FO4 (0.82V) and 7.23C Eu (0.82V). The design methodologies and strategic insights shared in this paper form a foundational basis for future enhancements in signal processing technologies, potentially driving these fields towards a path of accelerated, robust, and sustainable growth.

The demand for high-speed electronics is increasing, so this paper presents a new design for a 4-bit absolute value detector, an introductory module in high-speed electronics, using the basic gate circuit except for the transmission gate. This paper introduces the logical effort theory to calculate the worst-case delay of the designed circuit, combines the designed circuit with the relevant equation of the logical effort theory to analyze the delay influencing factors of the circuit, and verifies that the designed circuit achieves the minimum delay to realize the minimum delay design of the basic module. In this paper, the circuit is divided into an absolute value output device and a numerical comparator, but the topology used is a fusion circuit of these two parts, rather than simply connecting the two parts. This study achieves a branch-free circuit while maintaining the condition of minimizing the critical path.
