Abstract
An injection locked oscillator (ILO) circuit is disclosed. The ILO circuit may include a first clock injection stage including a first programmable inverter in series with a first self-biased inverter. The first injection stage may receive a first input clock having a first frequency and generate a first injection signal. The ILO circuit may further include a second clock injection stage including a second programmable inverter in series with a second self-biased inverter. The second injection stage may receive a second input clock signal having the first frequency and to generate a second injection signal. The ILO may further include a phase locked loop (PLL) stage including a multi-stage ring oscillator. The PLL stage may receive the first injection signal and the second injection signal and to generate an output clock signal based at least in part on the first frequency.
