Abstract
A temperature regulation system configured to regulate a temperature of the device may include first and second temperature-dependent current sources that are configured to generate first and second currents, respectively. The system may also include amplifiers configured to apply respective first and second amplification factors to the respective first and second currents to generate respective first and second intermediate currents. The system may also include a heater configured to generate heat based on the first and second intermediate currents and positioned such that the generated heat affects the device. Additionally, the system may include a controller configured to adjust the first and second amplification factors such that changes in the first and second currents, resulting from changes in temperature of the first and second current sources, result in changes to the heat generated by the heater to maintain an approximately equal temperature of the device.
