ABSTRACT:
A delay circuit is provided that delays the sampling signal by a selected amount in order to ensure that sampling does not occur concurrently with the occurrence of a noisy event. The noisy events on the IC tend to be periodic and occur at regular intervals. The invention allows the delay in the sampling signal to be adjusted such that sampling does not occur at the same time as the reoccurring noisy event. This ensures that the sample signals will not have noise in them resulting from the occurrence of the noisy event. In addition, the delay circuit is programmable to allow the amount of delay to be set on the fly.
