ABSTRACT:
A feedback control system and method thereof are provided. The feedback control method includes (a) comparing the level of a reference signal with the levels of first and second signals, (b) if the levels of the first and second signals are lower than the level of the reference signal, generating a first control signal, if the levels of the first and second signals are higher than the level of the reference signal, generating a second control signal, and if the level of the reference signal is between the level of the first signal and the level of the second signal, generating a third control signal, (c) controlling the level of an output signal in response to the first through third control signals, and (d) outputting the controlled output signal and generating the first signal and the second signal.
