Abstract

The mathematical model for determining locked ranges of frequency divider based on an injection locked relaxation oscillator (ILRO) is proposed. The proposed model can indicate that an appropriate frequency division ratio of the injection locked relaxation oscillator is an odd number. Locked ranges of the oscillator which are derived from the proposed model can not only be determined from the influence of a pure sinusoidal input signal but also from non-pure sinusoidal input signal. The verification of the proposed model is provided by using the simulation of the injection locked relaxation oscillator based on 0.35um CMOS of TSMC.
