Abstract :
A 285 GHz Sub Harmonic Injection Locked Oscillator (SHILO) is presented using a standard 65nm CMOS process. The architecture of this oscillator is based on the differential LC tank with push-push but adapted to obtain a third harmonic oscillation. The output power is -19 dBm at 285 GHz for a dc power of 70 mW. This oscillator offers a measured phase noise of -96.3 dBc/Hz at 10 MHz and -80.5 dBc/Hz at 1 MHz, and a tuning range from 284.2 GHz to 289 GHz. The SHILO can be locked all along the tuning range with an injection signal corresponding to one sixth of the output frequency. The chip size is 921×451 μm2.
