摘要

提出了一种工作频率为39.5 GHz和59.5 GHz的双模毫米波注入锁定分频器。在除以2和除以3模式下实现18%和20%的锁定范围,它从0.8 V电源消耗4 mW。采用大块CMOS 65nm技术实现,核心面积为0.03mm2。双模操作是通过差分直接注入和米勒电容去调谐实现的。本文还提出了两种新的优点值,以便对ilfd进行适当的比较。

A dual-mode mm-wave injection-locked frequency divider with greater than 18% locking range in 65nm CMOS
A dual-mode mm-wave injection locked frequency divider operating at 39.5 and 59.5 GHz is presented. Achieving a locking range of 18% and 20% in divide-by-2 and 3 modes, it consumes 4 mW from a 0.8 V supply. Implemented in a bulk CMOS 65nm technology, it occupies a core area of 0.03mm2. The dual-mode operation is enabled by differential direct injection and Miller capacitance de-tuning. Two new figure-of-merits for proper comparison of ILFDs are also presented.
