Study of amplification stage limitation of rotary traveling wave oscillators

In this work, an explanation for the frequency limiting factor through analysis and board level implementation of Rotary Traveling Wave Oscillator (RTWO) is proposed. We also established and demonstrate the relation between frequency limit and the amplification stage. To utilize RTWO for high frequency application, it was realized that, varying the ring size to achieve high frequency signals is governed by a length threshold which when exceeded contribute to signal instability and in some cases the possibility of no oscillation.
