| Summary: | The Arithmetic and Logic Unit (ALU) is a crucial logical element of real-time semiconductor devices. Conventional ALUs that are built using Complementary Metal Oxide Semiconductor (CMOS) technology exhibit increased power usage and processing delays. This investigation intends to develop a delay-controlled reconfigurable ALU employing advancements in FinFET (Fin Field Effect Transistor) Carbon Nano Tube Field Effect Transistor and (CNTFET) technology. The first development is the integration of Carry Output Predicted Adders (COPA) along with Carry Input Selective Adders (CISA) employing multiplexing selection circuitry, allowing the development of adders and subtractors with controllable delay. The Delay Controllable Reconfiguration ALU may be built by integrating arithmetic and logical functions. Nanotechnology-based techniques exceed traditional adders and subtractors regarding power efficiency and latency. The outcome results have been obtained with Cadence Virtuoso utilizing 18 nm finFET technological advances, having supply voltages between 0.8 V and 1 V and temperatures between -25 °C and 50 °C. Simulation findings indicate that the suggested 4-bit ALU has remarkable stability. The proposed CNTFET 4-bit Arithmetic Logical Unit (ALU) exhibits a 30 % decrease in power consumption and a 40 % decrease in delay time relative to existing 4-bit ALUs. |
