Circuit Design of a 4-bit Binary Counter Using D Flip-flops

Posted on November 5, 2015June 16, 2025 By vlsifacts 22 Comments on Circuit Design of a 4-bit Binary Counter Using D Flip-flops

Problem Statement: Design a circuit for an edge triggered 4-bit binary up counter (0000 to 1111). When it reaches “1111”, it should revert back to “0000” after the next edge. Use positive edge triggered D flip-flop (shown in the below figure) to design the circuit. Pin Input / Output Description D Input Data Input CLK…
