Abstract :
An all-digital on-chip jitter tolerance measurement technique for clock/data recovery (CDR) circuits is presented. A 6-Gbps CDR circuit with this proposed technique is realized in a 90-nm CMOS process. The measured jitter tolerance by using the testing equipment and the proposed technique correlate within 13 % in the frequency range of 178 kHz ~ 11.3 MHz. The measured peak-to-peak data and clock jitters are 15.56 and 13.3 ps. The power of the CDR circuit is 44.4 mW at a supply voltage of 1.2 V.
