Abstract

This article concerns the design of an inverting driver circuit having slow WV/Wt for the falling transition, during which any changes in the DC load current, e.g., for differing driver applications, may be accomodated without adverse effect on the transition. The designer is thus able to implement a slow WV/Wt circuit while having high DC drive. The drawing shows a high drive superslow driver circuit which allows any DC load current for slow WV/Wt. Key to its function is the operation of transistor T1 in saturation during the transition mode. When output A- falls to the zero level, T1 turns off automatically, turning off the transition control circuitry.
