摘要： Various apparatuses, methods and systems for boosting an amplifier slew rate are disclosed herein. For example, some embodiments of the present invention provide an apparatus including a pair of inputs connected to a pair of differential input devices in an amplifier, a current source, a first current path connected to the current source, a second current path connected to the current source and to the pair of differential input devices, a switch in the first current path, and a voltage difference signal connected between the pair of inputs and the switch. The voltage difference signal represents the voltage difference between the pair of inputs. The conductance of the switch is inversely proportional to the voltage difference signal.
