FinFET Fractional Order Injection Locked Oscillator

An injection locked oscillator was developed and simulated using 22 nm PTM FinFET model. Frequency spectra of the output were used to find he lock-in range. Using a fractional order capacitor showed a marked improvement in lock in range compared to integer order circuits with same Q factor. Compared to reducing Q factor in a linear tank circuit, the described approach provides an avenue to further extend the limited lock in range of injection locked oscillators.
