Patent ID: 8686789

Claim:
An amplifier system, comprising: an auxiliary feedback loop configured to operate upon an input signal if the amplifier system is operating under a power-up condition or a power-down condition, wherein a modulated signal is confined within the auxiliary feedback loop during the power-up condition or the power-down condition so that a plurality of transient signals coupled on the modulated signal are diverted away from an output device, and wherein the auxiliary feedback loop comprises: an auxiliary driver, wherein the auxiliary driver is configured to: operate at a first gain if the amplifier system is operating under the power-up condition or the power-down condition, and operate at a second gain if the amplifier system is operating under a normal condition, wherein the second gain is lower than the first gain; and a primary feedback loop configured to operate upon the input signal if the amplifier system is operating under the normal condition, wherein the modulated signal is introduced to the output device during the normal condition.
