Abstract
A linear power control loop for a power amplifier is disclosed. Embodiments of the invention linearly control the power amplifier output, prevent the power amplifier from failure induced by excessive supply current by reducing power amplifier bias current, and provide a mechanism to detect whether the power amplifier is operating in a saturation condition.
