摘要：

An injection-locked oscillator topology is presented, based on MOS switches directly coupled to the LC tank of well-known LC oscillators. The direct injection-locking scheme features wide locking ranges, a very low input capacitance, and highest frequency capability. The direct locking and the tradeoff between power consumption and tank quality factor is verified through three test circuits in 0.13-mum standard CMOS, aiming at input frequency ranges of 50, 40, and 15 GHz. The 40- and 50-GHz dividers consume 3 mW with locking ranges of 80 MHz and 1.5 GHz. The 15-GHz, divider consumes 23 mW and features A locking range-of 2.8 GHz.
