Abstract
A switched capacitor system with output glitch reduction step charges the switched capacitor by switching it to a first voltage level in a first phase, to an intermediate voltage level of a pre-charge node in a pre-charge phase and to the voltage level of the output node of the amplifier stage in a settling phase; the pre-charge node can be implemented at the input of the amplifier stage, the output of a preceding stage or at any other pre-existing suitable node in the amplifier system.
