As a particular highlight, the proposed SwCR multi-ratio converter enters conventional switched-capacitor operation as a low-power mode down to 0.5 mA once the switch conductance has reached the maximum limit. The presented converter e

Due to their higher quality factor, external inductors result in up to 4% larger power conversion efficiency.

Introduction, smartwatches, are an integral part of the Internet of things (IoT). The worldwide market for wearables is expected to grow at an annual rate (CAGR) of 11.3% from 2019 to 2025 to reach $62.82 billion by 2025. The power management in integrated state-of-the-art system-in-package solutions comprises i

Multi-Ratio Resonant Switched-Capacitor Converters, two flying capacitors. It comprises three conversion ratios, 1/3, 1/2, and 2/3, suitable to support the full Li-ion input voltage range. The analysis of the output resistance points to the optimum operation frequencies in the range of 30–50MHz. Various possible control methods are discussed such as
