POWER LIMITING FOR AMPLIFIERS

This application relates to methods and apparatus for power limiting for amplifiers. An amplifier is configured to receive an input supply voltage and to draw, in use, an amplifier input current resulting in an amplifier input power. A power limiter is configured to monitor an indication of the ampl...

Zusammenfassung:	This application relates to methods and apparatus for power limiting for amplifiers. An amplifier is configured to receive an input supply voltage and to draw, in use, an amplifier input current resulting in an amplifier input power. A power limiter is configured to monitor an indication of the amplifier input power, determine a first signal limit based on said indication of the amplifier input power and a pre-set limit and apply regulation to the input signal to provide a regulated input signal for input to the amplifier that does not exceed the first signal limit.
