Patent ID: 8686983

Claim:
A voltage regulator for controlling a reference pulse-voltage comprising a sequence of positive-negative pulses, the reference pulse-voltage defining an active range and a dummy range, the voltage regulator comprising: an acquisition unit adapted to receive each pulse of the reference pulse-voltage, and determine whether an alteration of the pulse is needed according to a predetermined calculation and generate a result message when it is determined that an alteration of the voltage pulse is needed; and a voltage control unit adapted to generate an output pulse-voltage corresponding to the reference pulse-voltage, wherein when no result message is generated, the voltage control unit is configured to output an output pulse having the same polarity as that of the received pulse of the reference pulse-voltage; and when the result message is generated, the voltage control unit is configured to output an output pulse having an opposite polarity dummy range to that of the received pulse of the reference pulse-voltage.
