“…To obtain RLC values with greater accuracy than other previous works [11,19,20,17,23] , the use of a 3D electromagnetic simulator was implemented. From the results presented, it is shown that the correct dimensioning of the resonator is vital in this type of oscillator.…”

“…In order to include the effects of the geometrical discontinuities, in [19] and [23] the transmission lines of the rotating ring were divided into uniform segments. However, the union of the different segments presents differences in contrast with the superposition of the effects by segments.…”

“…In [11], a rectangular topology was implemented and analytical approaches were used to obtain the RLC parameters. [19,20] implemented different RTWOs in a 180 nm technology with a frequency range from 2GHz to 12GHz, using a rectangular topology and a 2D electromagnetic simulator to extract the RLC parameters. In [17], RTWOs were designed in a 65nm technology achieving a frequency range from 110 GHz to 152GHz.…”

In this article, a new method to extract the RLC parameters from the structure of a Rotating Traveling Wave Oscillator (RTWO) is described. The use of a 3D simulator (EMPRO) allow us to develop a precise analysis of the impact of the topology, the geometrical discontinuities, and the dimensions of the transmission lines, on the performance parameters of the RTWO, i.e. frequency of oscillation and power consumption. The results show that a right angle discontinuity compensation can reduce the power consumption up to 3.34% and, for RTWOs with a frequency range between 11.4 GHz and 11.5 GHZ, narrow transmission lines (as the technology is able) can reduce the power consumption up to 98%. Additionally, it was observed that the topology used affects the performance parameters, as there are more folds and overlaps between metal levels in the RTWO structure, and the frequency increases by 2.9% while the power consumption increases by 10.52%.
