Abstract
A method for increasing responding speed and lifespan of a buffer includes detecting an edge of an input signal of the buffer, triggering a pulse signal with a predetermined period according to the detected edge, and driving the buffer for generating an output signal according to the pulse signal and the input signal.
Claims4
A buffer of buffering an input signal for generating an output signal from an output end, the buffer comprising:
- a buffer-driving circuit, for receiving the input signal so as to generate a voltage-sharing gate-driving signal and a transmitting gate-driving signal;
- a transmitting transistor, coupled to a first voltage source, for receiving the transmitting gate-driving signal;
- and
- a voltage-sharing transistor, coupled between the output end and the transmitting transistor, for receiving the voltage-sharing gate-driving signal;
- wherein when the input signal is a first voltage, the transmitting gate-driving signal is equal to a first predetermined voltage during a first predetermined period, the transmitting driving signal is equal to a second predetermined voltage beyond the first predetermined period.
