Differential Serpentine Delay Line Using Strongly-Coupled Turns with Timing-Offset Differential Signal

In this paper, the time-domain-through common-mode noise of the differential serpentine delay line using the strongly-coupled turns is investigated and found to be 0.0154 V. In order to further reduce the time-domain-through common-mode noise, a timing-offset differential signal is utilized. The differential serpentine delay line using the strongly-coupled turns with the timing-offset differential signal can greatly reduce the time-domain-through common-mode noise from 0.0154 V to 0.0065 V, which is more than one-half reduction.
