Abstract
A digital input signal is analyzed by a peak detector () configurable to trigger a first logic signal () if the peak detector detects the digital input signal level crossing a certain threshold. The threshold value can be modified by an overhead. The amplifier () employs a plurality of supply rails of differing voltages () as a function of the logic signals. A digital signal delay element () may delay the signal to allow sufficient time for the amplifier to switch between supply sources. A logic delay element () may delay transmittal of the first logic signal by the peak detector to compensate for signal delay caused by a filter. A hold element () ensures that the first logic signal is applied to the output amplifier for a given amount of time.
