Patent abstract

The present invention is directed to an amplifier, which is able to re-configure its internal protection circuits based on an output signal level. This allows the amplifier to apply the best protection level to the present operational condition. The protection level or threshold for protecting the amplifier is dynamically adjusted to a lower threshold level, thereby making it more sensitive in certain operating scenarios. In one embodiment of the present invention, a first current protection threshold is used to operate an amplifier in a first state. If an event occurs, the amplifier protection circuit is re-configured and the amplifier continues to operate with a second protection threshold in a second state.
