Abstract
The present invention provides an improved device for minimizing the time delays associated with turning on and off the power switches or power transistors in a standard totem pole configuration. An improved saturation detector monitors each transistor to determine when it is in saturation and generates a feedback signal which is combined with the input signal to generate the appropriate time delay needed to improve the switching time of the transistor.
