Adaptive active thermal control

Electronic devices produce heat as a by-product of normal operation. When electrical current flows through a semiconductor or a passive device, a portion of the power is dissipated as heat energy. If we do not allow the heat to dissipate, the device junction temperature will exceed the maximum safe...
