Abstract: A voltage regulator generates an output voltage that is a designed voltage level below the supply voltage. A reference voltage generator generates a reference voltage between ground and supply voltages. A voltage divider generates a feedback voltage between the supply and output voltages. An amplifier generates an amplifier output voltage based on a difference between the reference and feedback voltages. A buffer buffers the amplifier output voltage. A pass transistor receives the buffered voltage at its control node to sink an average load current appearing at the output node. A capacitor is connected between the supply and output voltages to provide a peak load current. A load-current-detecting transistor receives the buffered voltage at its control node to sense the load current. A compensation transistor compensates for leakage current. An internal load converts the sensed load current into a voltage control signal applied to the compensation transistor.

Abstract: A system, method, and computer program product for generating a regulated boosted load voltage. A comparator may use reduced versions of a reference voltage, a supply voltage, and a fed-back output load voltage to determine whether the output load voltage requires adjustment. If so, a controller may responsively vary the number of voltage boosting charge pumps connected in parallel to the load to best match a target voltage. The target voltage may be the reference voltage plus the supply voltage. A counter may track the number of active charge pumps, and may increment or decrement the number more slowly than the charge pumps operate. Loop gain may be limited by an integrating filter to prevent oscillation. The embodiments are of particular utility for signal conversion circuitry as they eliminate difficulties arising from gate-source voltage inadequacies and differences in switch transistors. A wider range of reference voltages may be accommodated.

Abstract: A method of generating a pumping voltage in an integrated circuit includes receiving an external clock signal from outside of the integrated circuit. The frequency of the received external clock signal is changed according to one or more modulation ratios, resulting in one or more respective modulated external clock signal. The external clock signal or one of the modulated external clock signals is then selected for use as a pump clock signal. The pump clock signal is used for driving the pump capacitance of a pump circuit for generating the pumping voltage.
