Abstract
An improved circuit and method is provided that can increase the slew rate of an operational amplifier without adversely affecting its response time. An operational amplifier comprises a large signal detector, a bias circuit having a bias override component, and a bias decay circuit. As a result, the operational amplifier provides the ability to control the increase in current supplied to its compensation capacitors while also providing a smooth transition to the decay phase. In accordance with an exemplary embodiment of the present invention, an exponential decay to the increased bias condition is provided.
