Abstract
The described devices, systems and methods include an integrator circuit having two separate operational modes to control a power output level delivered by the power amplifier to an antenna during start of a transmission burst. The first operational mode utilizes a wide bandwidth control loop to pre-charge a capacitor of the integrator circuit, which generates a pedestal voltage delivered to the power amplifier control input. The second operational mode utilizes a lower bandwidth control loop to ensure stable operation of the control loop during normal operation of the power amplifier.
