A hybrid DC-DC converter for sub-microwatt sub-1V implantable applications. Wieckowski, M., Chen, G. K., Seok, M., Blaauw, D., & Sylvester, D. In 2009 Symposium on VLSI Circuits, pages 166–167, June, 2009. abstract bibtex A DC-DC converter for sub-microwatt sub-1V loads is presented for efficient supply regulation of implantable devices powered by thin-film batteries. Using a hybrid, switched-capacitor architecture, it provides 444mV of DC output from a 3.6V DC source. Ultra-low power clock generation, level conversion, and linear regulation, combined with a unique startup circuit, enable a peak efficiency of 56% (4.6X ideal linear regulator) for loads from 5nA to 500nA. Fabricated in 130nm CMOS, it occupies 0.26mm2.
