| Zusammenfassung: | A voltage identification definition (VID) reference voltage generation circuit and a boot voltage generating method thereof are provided. In the boot voltage generating method, a VID reference voltage generation circuit is provided. The VID reference voltage generation circuit includes a preset voltage providing unit, a switch and a VID input signal detection unit. When the VID input signal detection unit detects no input of a VID signal, a control signal is generated to control the switch, such that the preset voltage providing unit provides an adjustable preset voltage. |
