摘要

Low-dropout Linear Regulators (LDOs) play an important role in the power delivery process within portable electronic devices, such as cellular phones and laptop computers. This paper introduces an LDO control technique based on a neuromorphic spiking compensation inspired by the human brain's data-driven communication. The presented voltage-spike detection method is based on capacitive coupling and a spike to current modulator, where the rapid transients at the LDO output are used to increase the quiescent current temporarily to enhance the dynamic response. Moreover, the presented technique reduces the size of the output capacitor in a typical LDO to enable its full integration within System-on-Chip (SoCs) while ensuring stability. Simulations in a 0.13 μm CMOS technology show over 85% reduction in overshoots and undershoots.
