Abstract: Over the past few decades, advances in IC technology have steadily shrunk feature sizes, necessitating the placement of more operational circuits on every chip. In designing digital circuits, a novel GDI based circuit is indeed the center of consideration, since it requires less power and achieves greater efficiency. GDI-based circuits mimic CMOS transistors but feature fewer transistors with a greater capacity for performance and reliability. This paper investigates the modelling and implementation of a Finite Impulse-Response (FIR) block developed utilizing GDI-based circuits as well as basic blocks. In this study, an eight-tap FIR architecture relying on GDI cells is created. The results reveal that even a FIR architecture with eight taps and GDI delivers reduced power consumption and performance improvement.
