Calculation of Average Power, Leakage Power, and Leakage Current of FinFET Based 4-Bit Priority Encoder

A 4-input, 3-output priority encoder, implemented in Hardware, often serves as a polling device that permits access to a single (hardware) resource whenever access requests initiated by multiple devices are received at its inputs, either on-chip or Off-chip. In this context, the design of a 4-bit (4-inputs and 3-outputs) FinFET priority encoder module, suitable for embedded system applications is presented in this work and it is found from Cadence simulations that the 4-bit dynamic FinFET priority encoder Average power dissipation is 11.56 nW, Leakage Current 26.19 pA and Leakage Power 131.1pW.
