Abstract

This paper presents an ultra-low swing level converter with integrated charge pumps that shows measured conversion in a 130-nm CMOS test chip from an input at a 145-mV swing to a 1.2-V output. Lowering the input allowable for a single-ended level converter supports energy harvesting systems that need to use very low voltages. View Full-Text
