A 2-ps Resolution Wide Range BIST Circuit for Jitter Measurement
ABSTRACT In this paper, we propose a novel built-in self-test (BIST) circuit to directly measure cycle-to-cycle jitter. The clock-under-test is under-sampled by this measurement circuit and the jitter values are transformed into digital words. A time-amplified technique is applied to obtain relatively higher resolution with smaller hardware overhead. Experimental results show that our proposed circuit is able to measure the jitter providing the clock frequency up to 2 GHz with resolution of 2 picoseconds.
Conference Paper: Experimental Results of Built-In Jitter Measurement for Gigahertz Clock[Show abstract] [Hide abstract]
ABSTRACT: This paper demonstrates a built-in jitter measurement (BIJM) circuit for Gigahertz clock. Based on a jitter-amplified technique with a pulse-removing mechanism, the pico-second level resolution is achieved in wide frequency range. The experimental results show the feasibility of the proposed BIJM circuit.Asian Test Symposium, 2008. ATS '08. 17th; 12/2008
