Abstract:
1. An amplifier comprising: (A1) a comparator; (B1) a first amplifier section including, a first switch coupled to be controlled by an output of the comparator, a first inner amplifier device coupled to a first output of the first switch, and a first outer amplifier device coupled to a second output of the first switch; and (C1) at least one second amplifier section each including, a delay element coupled to receive a comparator result from an immediately previous amplifier section, a second switch coupled to be controlled by a delayed output of the delay element, a second inner amplifier device coupled to a first output of the second switch, and a second outer amplifier device coupled to a second output of the second switch; wherein inputs of the amplifier devices are coupled in parallel to receive an input signal and outputs of the amplifier devices are coupled in parallel to provide an amplified output signal.
