An active termination circuit for clamping a signal on a transmission line in an electronic device is described. The active termination circuit is configured to clamp the signal on the transmission line to one of a first reference voltage level and a second reference voltage level. In one embodiment, the active termination circuit includes a bottom clamping transistor coupled to a first potential having a bottom clamping transistor control node arranged for clamping the signal at about a first reference voltage. The active termination circuit also includes a top clamping transistor coupled to a second potential having a top clamping transistor control node arranged for clamping the signal at about a second reference voltage as well as an inverter unit coupling the transmission line to stabilizing capacitors for stabilizing control node voltages.
