16.6 A Parameter-Free Runtime-Energy-Loss Optimizer Achieving 2.15% Error in Energy-Recycling Duty-Cycled Systems
Abstract
This work proposes a predefined-parameter-free runtime-Elossoptimizer for energy-recycling duty-cycled systems. By leveraging a 3 -level converter to recycle output-capacitance energy to the flying capacitor, it achieveslosswith increased robustness against battery voltage and leakage current variations. It achieves a quiescent current of 15 nA and an 80% efficiency at a 1µA load current, while eliminating sub-harmonic oscillation. It saves energy loss by up to 60% across a wide range of time spent in the sleep state.
