Abstract
A method and apparatus for controlling the temperature of a device, wherein said method and device includes a plurality of thermoelectric coolers with independent temperature feedback control loops monitors and controls the temperature of a device. One thermoelectric cooler coupled to the package of the device maintains a desired temperature of the package by utilizing a first independent control loop. A second thermoelectric cooler coupled to the device maintains a desired temperature of the device by utilizing a second independent control loop. The operating temperature of the package of the device is maintained as the temperature of the environment varies.
