Abstract:
An impedance matching circuit and an interface circuit are provided. The impedance matching circuit includes a reference-voltage generation circuit, a control-signal generation circuit, and a circuit subunit. The reference-voltage generation circuit generates a reference voltage. The control-signal generation circuit generates a plurality of control signals. The circuit subunit is coupled to the reference-voltage generation circuit and the control-signal generation circuit. The circuit subunit receives the reference voltage and the control signals. The circuit subunit includes a plurality of transistors. The plurality of transistors are turned on or off according to levels of the control signals, and the plurality of transistors provide an impedance which matches the impedance of a receiver when the interface circuit is powered. The reference voltage is provided to bulks of the transistors, so that the voltages of the bulks of the transistors are not equal to zero volts.

Claim (Index 17):
The interface circuit as claimed in  claim 15 , wherein the reference-voltage generation circuit comprises:\n a first resistor, a first terminal of the first resistor coupled between the second transistor and the third transistor in the first set of transistors; and a second resistor, a first terminal of the second resistor coupled between the second transistor and the third transistor in the second set of transistors, wherein a joint node of the second terminal of the first resistor and the second terminal of the second resistor is coupled to a reference-voltage output terminal which is used to output the reference voltage.
