Abstract
The buffer circuit includes a first transistor MPhaving a first end coupled to an output node Nand a control node coupled to an input node N; a second transistor MNcoupled to a second end of the first transistor MP; a third transistor MNcoupled to the second transistor MNsuch that a current in the third transistor MNis mirrored to the second transistor MN; a first sense device MPcoupled to the output node N; a first current source Icoupled to the output node N; a second current source Icoupled to the third transistor MN; a second sense device MPcoupled to the third transistor MN; and a bipolar device Qcoupled to the output node Nand having a base coupled to the second end of the first transistor MP
