摘要
In this paper, we present an infrastructure IP core to facilitate on-chip clock jitter measurement. In the proposed approach, the clock signal under test is delayed by two different delay values and the probabilities it leads the two delayed versions are measured. The RMS period jitter value can then be derived from the probabilities and the delay difference. Both behavior and circuit simulations are performed to validate the proposed technique and analyze the design tradeoffs, and a prototype chip has been designed for further validation.
