Abstract :
A frequency agile multiplying injection-locked oscillator (MILO) suitable for fast power cycling was designed in 65-nm GP CMOS. Edge detectors and multiple injection sites extend the lock range of the x4 multiplier to 36.3% of its free-running frequency. Lock range is further extended to 55.7% (2.3-4 GHz) by using 2 MILOs with adjacent lock ranges. Monitoring circuits identify the correct MILO and power-off the other MILO within 10 reference clock cycles.
