The paper presents an approach to optimize the performance of WiFi communication systems by using a low power ring oscillator delay cell. The proposed method is based on optimizing the design of the delay cell to achieve better power efficiency and signal quality. The study begins by presenting the design and simulation of the delay cell using a 45nm CMOS technology. The simulation results show that the proposed delay cell consumes very low power and delay. The paper then presents the design of a WiFi communication system using the proposed delay cell. The performance of the WiFi communication system is evaluated through various metrics such as bit error rate, power consumption, and signal-to-noise ratio. The simulation results indicate that the proposed approach outperforms the existing WiFi communication systems in terms of power efficiency and signal quality. Overall, the study demonstrates the potential of low power ring oscillator delay cells for optimizing the performance of WiFi communication systems.
