OUTPUT BUFFER HAVING A PRE-DRIVER TRANSITION CONTROLLER |
摘要 |
An output buffer (100) has a pre-driver circuit (120) for controlling a voltage transition of an output signal from an output driver transistor (150). The pre-driver circuit (120) provides an input that slightly leads the gate voltage of the output driver transistor (150). The pre-driver circuit (120) includes a configurable resistance circuit (480) that provides one resistance value during at the start of a signal transition and provides another resistance value near the end of the signal transition. A threshold detector (470) senses a voltage level of the input signal and switches from one resistance value to the other resistance value when the input signal crosses a predetermined voltage.
