摘要： A termination circuit is provided. The termination circuit includes a first receiving terminal, a second receiving terminal, a first resistive device, a second resistive device, a third resistive device, a fourth resistive device and a first switch. The first receiving terminal receives a first data signal. The second receiving terminal receives a second data signal. The first resistive device is coupled between a supply voltage and the first receiving terminal. The second resistive device is coupled between the supply voltage and the second receiving terminal. The third resistive device is coupled between the first receiving terminal and a first node. The fourth resistive device is coupled between the second receiving terminal and the first node. The first switch is coupled between the supply voltage and the first node.
