    Abstract: There is disclosed an integrated control circuit (3) for a charge pump (1). The integrated circuit comprises a first device (112,N1,N2,R,12) suitable for regulating the output voltage (Vout) of the charge pump (1) and a second device (113,M10,M11,C11,11) suitable for increasing the output voltage (Vout) from the charge pump with a set ramp. The integrated circuit comprises means (111) suitable for activating said first device and providing it with a first value of a supply signal (Ireg) in a first period of time (A) and suitable for activating said second device and for providing it with a second value (Iramp) of the supply signal that is greater than the first value in a second period of time (C) after the first in such a way that the output voltage of the charge pump ascends a ramp from a first value (Vlow) to a second value (Vhigh) that is greater than the first value, said second value being fixed by the reactivation of the first device.

    Abstract: A circuit for regulating an output voltage of a charge pump includes a regulator connected to an output of the charge pump. The regulator includes a voltage divider for dividing the output voltage. A filter has a first input for receiving the divided output voltage, a second input for receiving a control signal, and an output for providing a filtered divided output voltage. A comparator has a first input for receiving the divided output voltage, a second input for receiving a reference voltage, a third input for receiving the filtered divided output voltage, and an output for providing a digital signal based upon a comparison of the divided output signal, the reference voltage and the filtered divided output voltage. A logic control circuit has a first input for receiving a clock signal, a second input for receiving the digital signal from the comparator, and an output for providing a timing signal. A phase generator circuit has an input for receiving the timing signal from the logic control circuit for generating control phases for the charge pump.

    Abstract: The circuit has a voltage comparator (400) to compare a charge pump output voltage and a reference voltage. A clock control (425) conditions a charge pump clocking based on the comparison result. The comparator has a sampling unit for sampling the charge pump output voltage at a sampling rate. A frequency divider (415) and frequency selection state machine (410) controls the sampling rate based on voltage comparison result. Independent claims are also included for the following: (a) an integrated circuit including a charge pump voltage generator and a charge pump regulator circuit (b) a method of regulating an output voltage of a charge-pump voltage generator.
