摘要

The world is steadily moving towards automation in every trade, swiftly adopting it as the standard for information processing, archiving, and transmission. The major architects of this digitization are the integrated devices and their layouts. Based on recent analysis, a dynamic comparator is proposed to process traditional analoge data into digital format. In this case, an analog-to-digital converter (ADC) is essential for converting the analog signal. The demand for effective, space-efficient, and fast ADCs is driving the use of dynamic regenerative comparators, also known as clocked comparators, in practice. ADC devices play a significant role in low-power VLSI signal processing. Flash ADCs, for example, require numerous high-speed, low-power, and compact chip area comparators. The delay and speed of the double-tail comparator have garnered attention in the design process. This paper aims to analyze the delay of dynamic comparators and derive analytical formulations for it. Designers can obtain an intuitively designed traditional double-tail dynamic comparator with low power and efficient operation, even at low supply voltages, based on these assumptions. By adding a few transistors, power consumption can be drastically reduced. The simulation results were obtained using the Tanner EDA tool. Post-layout simulation using 180 nm CMOS technology confirms the analysis results of the proposed dynamic comparator. In this paper, a comprehensive examination of various comparator designs is presented, focusing on their power consumption and delay characteristics. The comparators, along with the suggested circuit, have been meticulously crafted and their transient responses simulated using the Tanner EDA suite. The simulations are carried out with 180 nm CMOS technology and a 1.7 V power supply voltage. Notably, the proposed circuit outperforms conventional latched comparators in terms of power efficiency, delivering higher speed with a minimal delay of just 5.22 s.
