In this paper we demonstrate that the steady state temperature increase due to the power dissipated by the circuit under test can be used as observable to test the gain of a 2GHz linear class A Power Amplifier. As a proof of concept, we use two strategies to monitor the temperature: a temperature sensor embedded within the same silicon die, which can be used for a BIST approach, and an Infra Red camera, with applications to failure analysis and product debugging.
