摘要： A voltage regulation method, a controller, and a chip are provided. In the method, a controller receives a digital first status representation value sent by a sensor; the controller determines, according to the first status representation value and at least one of a second status representation value or a first expected value, whether to regulate the supply voltage of the load, where the second status representation value represents a node voltage that is at a previous moment and that is of the detection point of the load, and the first expected value represents an expected value of a node voltage of the detection point; and when determining to regulate the supply voltage of the load, the controller sends a digital control signal to a power gating array, to control the power gating array to regulate the supply voltage.

摘要： A voltage generation apparatus includes: a controller, a first voltage division controller, a second voltage division controller, and a voltage detector. The first voltage division controller and a load are connected in series between an input power supply and ground. The second voltage division controller and the load are connected in parallel between ground and a connection point between the first voltage division controller and the load. The voltage detector is electrically connected to the load, and is configured to: detect a load voltage of the load, and feed back a detected value of the load voltage to the controller. The controller is configured to: receive the detected value fed back by the voltage detector, and generate a control signal based on the detected value. The control signal is used to control the first voltage division controller and the second voltage division controller.
