| 发明名称 | Pull-up circuit and related method | ||
| 摘要 | A device includes a pull-up circuit, first and second switches, and a feedback circuit. The pull-up circuit has a first terminal electrically coupled to a pad, and a second terminal electrically coupled to a first power node. The first switch has a first terminal electrically coupled to a first control terminal of the pull-up circuit, and a second terminal electrically coupled to a second control terminal of the pull-up circuit. The feedback circuit has a first terminal electrically coupled to the pad, and a feedback terminal. The second switch has a first terminal electrically coupled to the first control terminal of the pull-up circuit, a second terminal electrically coupled to the feedback terminal of the feedback circuit, and a control terminal electrically coupled to a second power node. | ||
