Accumulator dump is one of the tools used to convert serial data into parallel data on RFID communications. Accumulator dump on RFID communication consists of a series of counters and registers, where one of the supporting circuits in the counter and register is D flip-flop. D flip-flops are one type of flip-flop that is built using RS flip-flops. Discrete circuit design Master-slave flip-flops are built using NAND logic gates built using 0.35 µ m CMOS technology. The results of the D flip-flop circuit design are simulated using LT- SPICE software to see the speed of response and power dissipation in the circuit.
