Abstract
This paper presents a forwarded-clock receiver using a mixing cell integrated injection-locked oscillator (MIILO) and an I/Q generator based on injection-locked oscillator (IQGILO). By using MIILO, jitter tolerance is enhanced by about 1.8 times at high frequency compared to using a conventional injection-locked oscillator. In addition, the proposed receiver is robust against power supply induced jitter (PSIJ) caused by a clock distribution network because jitter tracking bandwidth of IQGILO is always lower than peak frequency of PSIJ regardless of latency mismatch between data and clock. The test chip achieves 9.6 Gb/s data rate with 0.96 mW/Gb/s and occupies only 0.0162 mm2 in a 1 V 65 nm CMOS.Keywords
