Abstract
The power supply is one of the major challenges for applications like internet of things IoTs and smart home. The maintenance issue of batteries and the limited power level of energy harvesting is addressed by the integrated micro power supply presented in this paper. Connected to the 120/230 Vrms mains, which is one of the most reliable energy sources and anywhere indoor available, it provides a 3.3V DC output voltage. The micro power supply consists of a fully integrated ACDC and DCDC converter with one external low voltage SMD buffer capacitor. The micro power supply is fabricated in a low cost 0.35 μm 700V CMOS technology and covers a die size of 7.7mm2. The use of only one external low voltage SMD capacitor, results in an extremely compact form factor. The ACDC is a direct coupled, full wave rectifier with a subsequent bipolar shunt regulator, which provides an output voltage around 17V. The DCDC stage is a fully integrated 4:1 SC DCDC converter with an input voltage as high as 17V and a peak efficiency of 45 %. The power supply achieves an overall output power of 3mW, resulting in a power density of 390μW/mm2. This exceeds prior art by a factor of 11.
