A Comparative Study on Different Parameters of Priority Encoder in Different Design Styles in the era of VLSI

Combinational logic circuits that compress two or more inputs into one or more outputs are called priority encoders. The most significant active line’s index is represented binarily as the priority encoder’s output. It is used to resolve errors with binary encoders that provide incorrect output when many input lines are active high. Priority encoder prioritizes every input level and assigns the priority level to each input if several input lines are active high concurrently. Priority encoders are designed using general methodologies such as CMOS, FINFET, and CNTFET. A comparative analysis is conducted on priority encoders based on the above-mentioned techniques. This study may help for further advanced research in the priority encoder domain.
