Title:
DEVICE FOR GENERATING VOLTAGE AND SEMICONDUCTOR CHIP
Document Type and Number:
WIPO Patent Application WO/2018/032766
Kind Code:
A1
Abstract:
A device for generating a voltage and a semiconductor chip, being able to enhance and expand the applicability and practicability of an on-chip power supply. The device for generating a voltage comprises: a controller, a first voltage division controller, a second voltage division controller and a voltage detector; the first voltage division controller being connected in series to a load (20) between an input power supply (VDD) and a ground (GND) terminal; the second voltage division controller being connected in parallel to the load (20) between a connection point between the first voltage division controller and the load (20) and the ground (GND) terminal; the voltage detector being electrically connected to the load (20), for detecting a load voltage (VVDD) of the load (20) and feeding back a detection value of the load voltage (VVDD) to the controller; and the controller being used for receiving the detection value fed back by the voltage detector, and generating, on the basis of the detection value, a control signal for controlling the first voltage division controller and the second voltage division controller to adjust the load voltage (VVDD) to a target value.
