Claim:
1. A temperature regulation system, comprising: a first current source configured to generate a first current that is positively proportional to temperature change; a second current source configured to generate a second current that is negatively proportional to temperature change; a first amplifier configured to apply a first amplification factor to the first current to generate a first intermediate current; a second amplifier configured to apply a second amplification factor to the second current to generate a second intermediate current; a third amplifier configured to output a heat current based on a sum of the first and second intermediate currents; a resistive element configured to generate heat based on the heat current; and a controller configured to adjust the first and second amplification factors to adjust the heat generated by the resistive element such that changes in the first and second currents result in changes to the heat generated by the resistive element to maintain an approximately equal temperature of an area surrounding a first device.
