  Operational-Amplifier-Based Realization of a 1-BitArithmetic Logic Unit: Design, Implementation, and Experimental Validation

  By Shrushti Amin, Aditya Chauhan, Himanshu Prajapati, Purvang Dalal, Mitul A. Shah

  Abstract: This work presents the design, construction, and experimental evaluation of a 1-bit Arithmetic Logic Unit (ALU) implemented entirely with operational amplifiers (op-amps), using only LM324 devices, passive components, and a dual-polarity ±12 V supply on a breadboard prototype. The ALU per- forms eight fundamental arithmetic and logic operations, addition, subtraction, AND, OR, NOT, NAND, NOR, and XOR, by combining op-amp comparator-mode logic gates with op-amp-based summing and difference amplifiers for …
