Abstract:
Voltage regulators, memories, and methods for providing a regulated output voltage are disclosed. For example, one such voltage regulator includes a comparator circuit, a driver circuit, an impedance circuit, and a modulation circuit. The comparator circuit generates an output voltage according to a difference between a reference voltage and a feedback voltage. The driver circuit is coupled to an output of the comparator circuit and drives the regulated output voltage at an output node according to the output voltage from the comparator circuit. The impedance circuit is coupled to the comparator circuit and provides the feedback voltage to the comparator circuit in response to a detection current from the output node. The modulation circuit is coupled to the impedance circuit and adjusts a modulation current component of the detection current to adjust the regulated output voltage.
