A 32-mV Supply Ring Oscillator Composed of Modified Schmitt Trigger Delay Cells for Integrated Start-Up Circuits in DC Energy Harvesting Systems

Implementing fully integrated start-up energy harvesting (EH) systems is very challenging. The most popular start-up circuit implementations use a low-voltage ring oscillator (RO). The characteristics of this RO rapidly deteriorate at VDD values below the transistor’s threshold voltage. A...
