A Novel Design of 100GHz Silicon-Based CMOS Injection Locked VCO

A 100GHz fundamental mode injection locked voltage controlled oscillator (ILVCO) is proposed to provide a lower phase noise frequency generator based on a clean reference frequency. The circuit is designed in a custom 65nm CMOS process with a self-designed inductor by HFSS and VCO power is 2.1mW under 1.2V supply voltage. Using a lower phase noise reference frequency, the ILVCO prototype generates about 100GHz central frequency with phase noise of -119dBc/[email protected], and the tuning range of fundamental output frequency is 93-109GHz.
