Abstract:
1. A single-stage folded cascode buffer comprising: an amplifier having a first input terminal, a second input terminal, and an output terminal coupled to the second input terminal of the amplifier; a first analog comparator comprising a first input terminal coupled to the second input terminal of the amplifier, a second input terminal coupled to the first input terminal of the amplifier, and an output terminal; a second analog comparator comprising a first input terminal coupled to the second input terminal of the amplifier, a second input terminal coupled to the first input terminal of the amplifier, and an output terminal; a first transistor comprising a first terminal coupled to a positive supply terminal, a second terminal coupled to the output terminal of the first analog comparator, and a third terminal coupled to the output terminal of the amplifier; and a second transistor comprising a first terminal coupled to the output terminal of the amplifier, a second terminal coupled to the output terminal of the second analog comparator, and a third terminal coupled to a negative supply terminal.
