Abstract
An output stage of a buffer or an amplifier connected to a switched capacitive load can operate in two phases to perform precharging and fine settling. The precharging and fine settling phases can be synchronized to the switching phases of the switched capacitive load connected to the amplifier. During the precharging phase, the output stage can be disconnected from the prior stages of the amplifier, and the output node of the amplifier can be connected to the switched capacitive load to precharge the capacitive load with the voltage already stored in the output stage. During the fine settling phase, the output stage can be reconnected to the prior stages of the amplifier, and the amplifier nodes can settle and get ready for sampling, which can occur at the end of the fine settling phase.
