Various methods and circuital arrangements for controlling an RF amplifier while reducing size, cost and power consumption are presented. Included is an amplifier controller unit that provides different current amplification stages, via corresponding calibration and control blocks, that can be used for calibrating an output power of the RF amplifier based on a reference current. Order of the current amplification stages starting from the reference current allow reduction in size, cost and power consumption. A fixed or programmable offset current may be added to an output current provided by a current amplification stage.
