Abstract
A unit cell for a programmable termination circuit in an integrated circuit and a method for programming such termination circuit are described. In an embodiment, such unit cells may have three n-type and three p-type transistors. A first transistor is coupled to receive a first float control signal. A second transistor is coupled to receive a second float control signal. The third and fourth transistors are coupled to receive a first termination voltage control signal. The fifth and sixth transistors are coupled to receive a second termination voltage control signal. The first float control signal and the second float control signal are a pair of complementary signals.
