IC for Low Voltage and Self-Starting Thermoelectric
Energy Harvesting
Technology Description Researchers at OSU have developed an integrated circuit that can cold start a DC-DC boost converter on a very small input voltage and combines a unique charge pump and very efficient DC-DC boost converter to maintain on-going operation at even lower input voltages. This IC is battery-free and can be made with conventional CMOS...
