Abstract
An amplifier circuit comprising: a first-stage residue-reduction storage unit; a final-stage residue-reduction storage unit; and a switching network. The switching network is operable to control the amplifier circuit according to the following operational configurations: a first residue-reduction configuration; a second residue-reduction configuration; and an operational configuration. Such an amplifier circuit uses a low number of residue-reduction steps to reduce global residual voltage to a very low level when the amplifier circuit is subsequently used in the operational configuration.
