PROBLEM TO BE SOLVED: To provide an apparatus or the like for reducing electrical over-stress of transistors and for generating output with a deterministic duty cycle for load independent buffers.SOLUTION: An apparatus comprises a feedback capacitor electrically coupled between an input terminal and an output terminal of a buffer; and a switch, electrically parallel to the feedback capacitor and operable to electrically short the feedback capacitor in response to a control signal. The switch causes deterministic voltage level on the input terminal of the buffer.SELECTED DRAWING: Figure 2
