Abstract
Mobile devices such as mobile phones include amplifiers for example audio and RF amplifiers which may consume a significant amount of the available power supplied by a battery. An amplifying systemfor a mobile device is described the amplifying system comprising a current monitorarranged between a first supply node and a second supply node and operable to monitor a current flow between the first and second supply nodes and to output a monitored current value; a peak current limiterconfigured 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; a controller coupled to the current monitor output and configured to control the peak current limiter. The amplifying system can dynamically manage the peak current available to the amplifier dependent on the load current being supplied by a battery.
