A lower-power, high-sensitivity injection-locked oscillator for 60 GHz WPAN applications

This article presents a 60 GHz low-power injection-locked oscillator in TSMC 65 nm technology. By using the frequency sweeping technique, a simulated 7 GHz total locking range is achieved, which covers the entire 60 GHz ISM band. The simulated settling time is less than 2 ns for each sweeping step with -60 dBm injection power. The DC power consumption is 1 mW of the oscillator core, and 5 mW in total for the input and output buffers, which are mainly used for the matching purpose
