Abstract
An operational amplifier input stage includes a first differential input transistor and a second differential input transistor receiving a differential input voltage. A first translinear loop is coupled to the first differential input transistor and a second translinear loop is coupled to the second differential input transistor. The first and second translinear loops are operable to supply an instantaneous current to the respective first and second differential input transistors to sufficiently charge capacitances therein during slewing conditions.
