Abstract: A buffer circuit is provided to output an output signal at an output node. The buffer circuit includes first and second inverters and first and second switches. The first inverter inverts an input signal. The second inverter is coupled between the first inverter and the output node. The first switch is coupled between a first voltage source terminal and the output node. The second switch is coupled between the output node and a second voltage source terminal. First and second voltages are respectively provided to the first and second voltage source terminals. In response to the input signal switching to a first level from a second level, the first switch is turned on to pre-charge the output node. In response to the input signal transiting to the second level from the first level, the second switch is turned on to pre-discharge the output node.
