Background: The frequency divider is a critical element in ultra-high-speed applications of communication systems, which provides an important benchmark for the performance of high-speed technology. These frequency divider designs are based on CMOS technology and contain many newer gate configurations and device functions, which achieved in terms of high speed, low power dissipation and reduced chip size, which is a negative element that should be lowered at all costs to maintain high speed technological requirements. Objective: To design a 1/3 and 1/5 frequency divider circuit by using proposed JK flip-flop. To anaylse the power dissipation, maximum operating frequency and propagation delay. Results: Compared with conventional techniques, the proposed JK Flip-Flop based frequency divider circuit has a maximum operating frequency of 59.38GHz with 0.192 mW of power utilisation. Conclusion: the proposed design outperformed a comparable CMOS circuit in term of power dissipation, propagation delay, layout area and operating frequency. The circuit is designed using digital schematic CAD tools, while a layout editor is used for the layout generation. Layout versus simulation (LVS) is performed by a BSIM 4 analyser. This paper also presents the result of parametric analysis, including measured power dissipation and leakage current through the load capacitance and supply voltages that gives better performance than existing circuits.
