This paper presents a novel design of a ring oscillator (RO) producing eight phases output with accurate signal phase adjustment. By using the pulse injection technique, the RO phase noise has been strongly suppressed. In addition, a novel phase control technique is proposed for the implementation of the phase modulation. The proposed RO achieves a phase noise of -131.5 dBc/Hz @1MHz offset and figure of merit (FoM) of -199.25 dBc/Hz. This RO consumes a 3.4 mW of power from a 1.8V power supply while having an oscillation frequency of 4.5 GHz and a locking range of 540 MHz in CMOS 0.18 um technology. |
