ABSTRACT:
A bootstrap circuit comprising a capacitive device connected between an input line and an output line to boost a signal from the input line, a first voltage supply path being selectively driven in response to a voltage on the output line to transfer or block a supply voltage from a supply voltage source to the output line, a second voltage supply path connected in parallel to the first voltage supply path to transfer or block the supply voltage from the supply voltage source to the output line, and a controller for controlling the second voltage supply path in response to the signal from the input line. According to the present invention, the bootstrap circuit enhances a response speed of an output signal with respect to an input signal. Therefore, the bootstrap circuit can boost the input signal stably and accurately regardless of an impulse noise component.
