A New DC-DC Converter Architecture for Low-Power, High-Resistance Thermoelectric Generators for Use in Body-Powered Designs
This thesis presents a low power batteryless DC-DC converter suitable for harvesting energy from high impedance TEGs for the use in body powered electronics. The chip has been fabricated in a 130nm CMOS technology. To meet the power demands of body powered networks, a novel dual-path architecture capable of efficiently harvesting power at levels below 5 μW has been developed. To control the converter, a low power control loop has been developed. The control loop features a low-power oscillator and pulse counting system capable of matching impedance with high impedance thermoelectric generators (TEGs). The system consumes less than 900nW of quiescent power and maintains an efficiency of 68% for a load of 5 μW.
