In this paper, an 8GHz 16th sub-harmonic Injection-Locked Oscillator based on LC-oscillators and pulse generators is presented. It has been fully implemented in a VLSI 65nm CMOS technology from STMicroelectronics and is dedicated to a double-loop frequency synthesizer. Under a nominal power supply of 1.2V, the ILO core dissipates 20mA (without buffers) for a measured phase noise of -107dBc/Hz at 100kHz offset from the 8GHz carrier. It also provides a synchronization bandwidth of 350MHz, thanks to a double synchronization network.
