N2 - A linear model for feed forward ring oscillators (FROs) is developed and the oscillator characteristics are analyzed using the model. The model allows the prediction of multiple oscillation modes as well as the oscillation frequency of each mode. Prediction based on the model agrees well with SPICE simulation results. Using the model, a five-stage FRO is optimized for its highest oscillation frequency. Post-layout simulation shows that 12-GHz oscillation frequency is achievable with a typical 0.18-μm CMOS technology.
