RF-power amplifiers are essential for all wireless communication systems. Modern RF-power amplifiers incorporate design margins to compensate for process variations and environmental influences. The design margin required in the RF-power amplifier both lowers its performance and increases its cost. To mitigate the issues of process variation and environmental influences self-healing can be applied. With self-healing a control loop is created that measures operating condition of the RF-power amplifier and uses the acquired information to correct for unwanted behavior due to process variations and environmental influences.
The aim of this research is to design a power and area efficient integrated self-healing RF-power amplifier
