Abstract :
In the present paper we analyze that DC temperature measurements of the silicon surface can be used to monitor the high frequency status and performances of class A RF Power Amplifiers. As a proof of concept, we present experimental results obtained with a 65 nm CMOS IC that contains a 2 GHz linear class A Power Amplifier and a very simple differential temperature sensor. Results show that the PA output power can be tracked from DC temperature measurements.
