Calculation of Power Delay Product and Energy Delay Product in 4-Bit FinFET Based Priority Encoder

Abstract

Priority encoder converts multiple binary inputs into binary representation of the index of active input bit with the highest priority. It is used where more than one device want to access the system, it decides the priority of the device to be serve by the system. Priority encoders are used when multiple devices have to share common resources. Several researches are made on these encoders but found no research work on FinFET based Priority encoder. The FinFET device has gained very much attention on recent VLSI designs and FinFET is the substitute for bulk CMOS at nano-scale because of its high short channel effect immunity, scalability and lower leakage power consumption. In this paper, a 4 input-3 output priority encoder is implemented using FinFET design.
