摘要：

This paper presents a PVT-tolerant wideband injection-locked frequency divider with a 0.1 GHz to 67 GHz frequency range, implemented in 28nm CMOS. The design uses complementary injection to achieve a wider locking range and a supply-based PVT-compensation to drastically reduce PVT sensitivity. A replica-based automatic tuning scheme is introduced to achieve a very wide frequency range without the need for manual tuning, while also increasing the sensitivity and minimizing the additive jitter. The resulting design achieves a locking range of 199.4% and an additive jitter of just 17 fs at an input frequency of 30 GHz.
