ABSTRACT:
A resistive divider for a voltage multiplier circuit minimizes output voltage overshoot by capacitively coupling the tap point of the resistive divider to the output terminal of the voltage multiplier circuit via the parasitic capacitance of the resistive divider. For a resistive divider that includes a resistive structure formed over a dielectric layer formed on a doped well, this capacitive coupling can be performed by connecting the well to the output terminal of the voltage multiplier circuit. This capacitive coupling improves the response time of the resistive divider, so that a scaled test voltage read from the tap point varies more rapidly than the elevated output voltage of the voltage multiplier circuit. Therefore, the scaled test voltage provides charging control that increases the elevated output voltage in gradual increments that prevent the elevated output voltage from exceeding a target output voltage.
