Abstract
A termination circuit includes a pMOS transistor configured to have a source connected with a signal terminal outputting or inputting a transmission signal, a drain connected with a grounding line, and a gate receiving a control signal, the pMOS transistor being turned on when enabling a characteristic impedance matching function and being turned off when disabling the matching function; and an inductor and a capacitor configured to be connected with the signal terminal for matching characteristic impedance.
