Abstract
A DC-coupled buffer is provided with two switch transistors controlled by a delayed version of an output signal for the DC-coupled buffer. A first one of the switch transistors functions to cut off a current discharged into ground that would otherwise flow while an input signal for the DC-coupled buffer is discharged. A remaining second one of the switch transistors functions to increase the operating speed of the DC-coupled buffer.
