Abstract:
A clock jitter measurement circuit includes: an internal signal generator configured to generate a single pulse signal and an internal clock signal which are both synchronized with an input clock signal received by the clock jitter measurement circuit, a plurality of edge delay cells serially connected to each other and configured to generate a plurality of edge detection signals respectively corresponding to a plurality of delay edges obtained by delaying an edge of the internal clock signal, a plurality of latch circuits configured to latch the single pulse signal in synchronization with the plurality of edge detection signals and output a plurality of sample signals, and a count sub-circuit configured to count a number of activated sample signals of the plurality of sample signals and output a count value based on the counted number of activated sample signals.

Claim (Index 23):
A method, comprising:\n generating a plurality of edge detection signals from an input clock signal, wherein the edge detection signals each detect an edge in an internal clock signal, which is synchronized to the input clock signal, at a corresponding point delayed in time with respect to the edge in the internal clock signal; counting a number of the plurality of edge detection signals which exhibit a transition within a defined time interval which is proportional to a period of the input clock signal; and estimating a jitter in the input clock signal from a result of the counting.
