Energy harvesting could get a boost from an analog circuit that harnesses the lowest power outputs from individual photovoltaic cells, thermoelectric generators and electromagnetic sources, according to its developer. Advanced Linear Devices Inc. (ALD, Sunnyvale, Calif.) said it increased the output of green power sources with an array of zero-threshold transistors called a super voltage booster. The energy-harvesting modules can now harness even the trace output power from sources under 1 volt.
