A 385μm × 385μm 0.165 V 0.27 nW Fully-Integrated Supply-Modulated OOK CMOS TX in 65nm CMOS for Glasses-Free, Self-Powered, and Fuel-Cell-Embedded Continuous Glucose Monitoring Contact Lens

Abstract

This work presents world's lowest power consumption sub-mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> supply-modulated CMOS OOK transmitter for enabling self-powered continuous glucose monitoring contact lens. By introducing self-oscillating voltage doubler and charge pump, compact, low-voltage, low-power supply-modulated OOK transmitter become available. By prototyping 385 μm × 385 μm testchip in 65nm standard CMOS technology, 0.27 nW under 0.165 V performance and self-powered operation using 2 mm × 2 mm solid-state glucose fuel cell were sucessfully demonstrated.
