The field of Integrated Circuit (IC) technology has seen amazing developments over the last few decades, resulting in a constant reduction in the size of circuit features. This continual tendency has demanded the introduction of IC-741-based circuits into each Integrated IC, reflecting the electrical design's continuous progress. During the complex process of digital circuit design, special attention is paid to new circuits that use Dynamic Threshold Metal-Oxide Semiconductor (DTMOS) technology. Because of its unique capacity to produce higher efficiency while consuming less power, DTMOS-based circuits have gained major importance. These circuits mimic the behaviour of CMOS transistors while using only two transistors to maintain good performance and resilience. The proposed study focuses on the design, modelling, and implementation of a Finite Impulse-Response (FIR) filter using DTMOS logic in conjunction with basic building blocks. Within the purpose of this inquiry, an 8-Tap FIR structure based on DTMOS chambers is constructed. The study's findings highlight the benefits of incorporating DTMOS logic into an eight-tap FIR architecture, providing significant increases in both power efficiency and overall performance. This study adds to the ongoing investigation of cutting-edge technologies that improve the capabilities of digital circuits.
