Summary: | High speed design suffers from serious signal integrity issues, resulting in distortion of
the high speed signals and leading to unreliable operation. Signal integrity issues occur
due to many reasons; however, it is ringing in high speed digital circuits which distort
the signal most severely. Unreliable operation occurs because the distorted signals cause
erroneous and false switching in high speed circuits. The main focus in this report is to
understand the causes for ringing in high speed signals, as well as to evaluate different
solutions to minimize ringing in active circuits. In order to investigate ringing, a trace is
first studied. Next, ringing in an active clock driver is investigated, and finally, different
techniques are evaluated to minimize the ringing in actual systems. |
