ABSTRACT:
A generator produces a high voltage from a power supply voltage. The generator includes an oscillator for producing a driving signal, and a charge pump for producing the high voltage from the power supply voltage based upon receiving the driving signal. The charge pump includes n series-connected voltage step-up stages including a first step-up stage receiving the power supply voltage and a last step-up stage producing the high voltage, at least one replacement step-up stage, and a switching circuit. The switching circuit replaces a damaged one of the n series-connected voltage step-up stages with the at least one replacement stage when a warning signal is received. A voltage regulator produces an activation signal for activating the oscillator if the high voltage is below a desired value. A detector produces the warning signal if the charge pump is defective.
