N2 - Due to the increase in current consumption caused by higher integration of high performance and diverse functioning chips in mobile phones, it has become more important to design a stable global power distribution network. When the operation of high-power functions overlap and there is excess peak current consumption, a sudden voltage dip occurs from the battery to the power management unit. In this paper, we propose an active compensator method to prevent voltage dip below the under-voltage lockout (UVLO) threshold voltage in the mobile phone power distribution network. To design the active compensator circuit, a simulation model for the power delivery network is developed based on the load current profile, power delivery network PCB layout, and Lithium-Ion battery model.
