Claim:
1. An amplifying system for a mobile device, the amplifying system comprising: a first supply node operably coupled to a battery, the first supply node to supply a battery current to the battery; a current monitor arranged between the first supply node and a second supply node and operable to monitor a current flow between the first and second supply nodes and to provide a monitored current value; a peak current limiter configured to limit an amplifier current to an amplifier to not exceed a maximum peak current value and coupled to a one of the first supply node and the second supply node; and a controller coupled to the current monitor output, the controller configured to control the peak current limiter, and to set the maximum peak current value of the peak current limiter in dependence on a difference between the battery current and the amplifier current.
