Patent number: 9634662Abstract: A pull-up resistor circuit is provided for an IC, including a voltage source, a voltage output for providing a first voltage to supply power for providing a second voltage for an input/output (I/O) port of the IC, a first PMOS transistor, a second PMOS transistor and a control signal generator. The first PMOS transistor and the second PMOS transistor are connected in series to provide pull-up resistance, where the first PMOS transistor is coupled to a first control signal to control a pull-up function of the pull-up resistor circuit in a normal mode. Further, the control signal generator is for generating a second control signal coupled to the second PMOS transistor to control a bias voltage of the pull-up resistor circuit to prevent a reverse current from the voltage output to the voltage source under a high-voltage-tolerant mode when the second voltage is higher than the first voltage.Type: GrantFiled: November 19, 2014Date of Patent: April 25, 2017Assignee: SEMICONDUCTOR MANUFACTURING INTERNATIONAL (SHANGHAI) CORPORATIONInventors: Kai Zhu, Jie Chen, Wenjun Weng, Shanyue Mo, Zhiguang Guo
