NVB TRICKLE-CHARGER SYSTEM WITH BUILT-IN AUTO-DUMMY-LOAD USING SI-MOS-SUB-VTH MICRO-POWER PYROELECTRICITY

摘要

Disclosed herein is a device, system, and method for a trickle charging system of non- inductive voltage boost (NVB) converter with built-in auto-dummy-load (ADL) for wide- range of charge storage devices i.e. small button-cell type batteries and super-caps using micro power pyro-electricity at Si-MOS sub-threshold voltage. A VLSI configuration of the system is also disclosed in embodiments. The system converts the pyro-electric material at MOS sub-threshold 0.37V for optimizing to the battery charging level at 1.45V. This system was proven at hardware level and found to be 98.8% power efficient. The designed IC can charge independently without any external components for up to luW max, but able to charge up to 20uA with external components. Thus it is considered to be a very versatile design.
