title = "Sub-30-mV-Supply, Fully Integrated Ring Oscillator Consisting of Recursive Stacking Body-Bias Inverters for Extremely Low-Voltage Energy Harvesting",
abstract = "This paper presents a ring oscillator (ROSC) consisting of recursive stacking body-bias inverters (RS-BBIs) for low-voltage energy harvesting. The RS-BBI is based on the conventional stacked body-bias inverter and consists of additional inverters stacked at the top and bottom of the inverter recursively. The RS-BBI increases the transconductance of MOSFETs and suppresses the leakage current due to its stacking structure, and increases the on-current of MOSFETs with the body-bias technique. The minimum supply voltage V D D,can be reduced by increasing the number of stacking inverters. Measured results indicate that our ROSCs using the RS-BBIs were able to operate at lower supply voltage as the number of stacking inverters increased. The measured lowest VDD, min was 26 mV even though not all chips were able to oscillate. All chips oscillated successfully at 30 mV.",
