Abstract
A slew rate enhancing circuit is disclosed. A current mirror circuit generates a mirrored current according to a current source, and the mirrored current is adaptively provided for an amplifier. A switch circuit is electrically coupled with the current source and the current mirror circuit. The switch circuit includes a first branch and a second branch that are coupled in parallel, wherein passage of the first branch and passage of the second branch are respectively controlled by a first switch and a second switch according to the non-inverting input voltage and the inverting input voltage.
