Higher decimal numbers can be handled more efficiently using binary-coded decimal (BCD) numbers than conventional binary numbers. In this study, we propose 4-bit full adder as well as 4-bit BCD adder using two 4-bit full adders (FAs). Waveguide-based silicon microring resonator all-optical switch is utilized to design the proposed circuits. The complexity of both the designs is very less as the required components is exceptionally reduced as compared to existing reports. The all-optical microring resonator is intriguing due to its ability to achieve ultra-high speeds, consume extremely little energy, and be very small in size which is necessary for optical integrated circuits. The data rate of the proposed design is nearly 260 Gbps. The required pump power for switching is only 1.86 mW for microring resonator based switch which is very less comparatively. The design of 4-bit FA and 4-bit BCD adder are envisaged in MATLAB simulation platform. Figure of merits of the proposed circuits is achieved numerically through simulation which is used to characterize the performance of the proposed designs. The obtained values of extinction ratio and contrast ratio are much higher for the proposed design and the values are 30.01 dB and 31.02 dB, respectively. The value of AM is 0.27 dB which is less than 1 dB. The on–off ratio of the MRR is 36.8 dB which is much higher than expected. [ABSTRACT FROM AUTHOR] |
