Abstract
Disclosed herein are differential amplifiers for improved slew performance. In some embodiments, a differential amplifier may receive positive and negative input signals at first and second transistor branches, respectively; provide a dynamic bias current to the first and second transistor branches, responsive to the positive and negative input signals; and provide positive and negative output signals at the second and first transistor branches, respectively.
