Abstract
A battery operated portable communication device is provided with improved transmitter current limit stabilization via a current limit stabilization circuit operatively coupled to the battery and a DC-to-DC converter of the transmitter. The current limit stabilization circuit provides a variable stabilizing reference voltage which is directly proportional to the supply voltage. The current limit stabilization circuit generates a voltage limit output voltage that controls both the power to the transmitter (120) and limits current to the transmitter.
