Abstract
A circuit topology to reduce ringing and the strength of unwanted signals includes a signal transmitting terminal, a first signal receiving terminal, and a second signal receiving terminal. The signal transmitting terminal receives a first DC voltage via a first node and a first resistor. The first node is electrically connected to a second node via a third resistor and an energy consuming element. The energy consuming element weakens the voltage level of noise signals on the second signal receiving terminal, therefore, signal reflections from the second signal receiving terminal are reduced, and signal integrity at the first signal receiving terminal is improved.
