Abstract :
For high-speed analog and mixed signal circuits, on-chip clock jitter measurement has been a challenge in recent years. Circuit resolution, chip area, and frequency range are critical specification for built-in-test (BIT) circuit design. In order to fulfil these requirements, the self-sampled Vernier delay line (VDL) structure is proposed. Comparing with traditional VDL structure, there is no more jitter free sample clock used in this design. When the proposed circuit is designed in 14 ps circuit resolution, only 500mum*750mum chip area is used for 100 MHz to 400 MHz measurement range in TSMC 0.35mum CMOS process
