Termination for complementary signals

摘要

Apparatuses including termination for complementary signals are described, along with methods for terminating complementary signals. One such apparatus includes a termination transistor including a first node configured to receive a first complementary signal and a second node configured to receive a second complementary signal. A regulation circuit can generate a regulated voltage to render the termination transistor conductive with a substantially constant resistance. In one such method, a first complementary signal is received at a drain of a termination transistor and a second complementary signal is received at a source of the termination transistor. Energy of the complimentary signals can be absorbed when the termination transistor is rendered conductive. Additional embodiments are also described.
