Termination circuit

A termination circuit, comprising:

• a termination resistor, having a first end coupled to a signal pad;
• a first switch circuit, having a first end coupled to a second end of the termination resistor;
• a second switch circuit, having a first end coupled to a second end of the first switch circuit, wherein a second end of the second switch circuit is coupled to a reference voltage line, and the second switch circuit is controlled by a control signal;
• and
• a control circuit, configured to control the first switch circuit, wherein
• during a period when the control signal turns on the second switch circuit, the control circuit transmits a bias voltage to a control end of the first switch circuit to turn on the first switch circuit;
• and
• during a period when the control signal turns off the second switch circuit, the control circuit transmits a voltage of the first end of the first switch circuit to the control end of the first switch circuit to turn off the first switch circuit.
