ABSTRACT:
In order to reduce the amplitude of an overshoot/undershoot voltage and clamp a signal at a constant voltage level over a wide temperature range, a bias voltage having a clamping element operating at a boundary region between ON and OFF states is applied to a control electrode node of the damping element. When the difference between the voltage of a signal line and the bias voltage is higher than a P-N junction built-in voltage, the clamping element is rendered conductive to clamp the overshoot/undershoot voltage.
