Termination circuit
Abstract:
A termination circuit, including a termination resistor, a first switch circuit, a second switch circuit, and a control circuit, is provided. A first end of the termination resistor is coupled to a signal pad. A first end of the first switch circuit is coupled to a second end of the termination resistor. A first end of the second switch circuit is coupled to a second end of the first switch circuit. A second end of the second switch circuit is coupled to a reference voltage line. During a period when the second switch circuit is turned on, the control circuit turns on the first switch circuit with a bias voltage. During a period when the second switch circuit is turned off, the control circuit turns off the first switch circuit with a voltage of the first end of the first switch circuit.
