A 73 to 83 GHz injection-locked oscillator (IJLO) is realized in TSMC 65-nm CMOS technology. By using the frequency-sweeping method, a 10 GHz total locking range is achieved with -35 dBm injection power. The power consumption is 9 mW from a 1-V supply. Additional 4 mW and 6 mW are consumed for the input and output buffers respectively for the measurement purpose. The measured sensitivity of the IJLO is -60 dBm. The output power measured at the 50-Ohm load is higher than -10 dBm, and the simulated total settling time of the IJLO is less than 10 μs. The effective core area of the chip is 0.055 mm2.
