Abstract
A system can control, with a positive temperature-voltage correlation, an output of a voltage regulator with a Peltier device. The Peltier device can receive heat from a heat-producing electronic device, and can have a positive terminal and a negative terminal. A voltage regulator circuit can include a driver device electrically coupled to an input voltage and an output terminal electrically coupled to one of the Peltier device terminals. The voltage regulator circuit can also include a differential amplifier electrically coupled to a reference voltage, an input electrically coupled to another Peltier device terminal and an output electrically coupled to the driver device. The differential amplifier can, in response to a voltage produced by the Peltier device, modulate, with a positive temperature-voltage correlation, an output voltage on the output terminal of the driver device.
