Abstract

Energy efficiency is a primary goal in modern digital system design, especially as IoT, mobile, and AI applications demand low power consumption alongside high performance. To optimize energy consumption, both supply voltage (V_DD) and threshold voltage (V_th) need to be tuned to operate at the Minimum Energy Point (MEP), where dynamic energy (E_dyn) and leakage energy (E_leak) are optimally balanced[1]. Achieving MEP under varied environmental and workload conditions is essential for sustaining energy-efficient performance across diverse applications, driving the need for Minimum Energy Point Tracking (MEPT) mechanisms [2]-[6].
