    Abstract: A system and method are used to accelerate settling or steady state of an amplifier in an amplifier system. This is used to ensure the amplifier reaches steady-state within a specified time period from stand-by or another state without using more current than is needed for steady-state. A comparator in a common-mode feedback system compares a desired amplifier output signal to one or more nodes of the amplifier. A result of the comparison is compared to a threshold value using a comparator in a settling acceleration system. If the result crosses the threshold, a controller turns on a driver in the settling acceleration system. The driver pulls on one or more nodes of the amplifier, which, along with a driver in the amplifier system pulling on the node, quickly brings the amplifier to settling or steady state.
