Abstract

Ring oscillators are used in many applications, but for all of them the system output is a clock signal with a 50% duty cycle. Our work sets the analytical basis for understanding and designing a ring oscillator whose outputs are clock signals with fully-configurable duty cycles different from 50%. We present two models in order to vary the output duty cycle with reduced area overhead: the first model is based on the layout design, focusing on the transistor sizing of each inverter gate; and the second model establishes a relation between the output duty cycle and different bias voltage schemes. These models are validated by simulation with a 40 nm commercial technology. The simulations include the impact of variability and the characterization of the oscillator phase noise. We also discuss the utilization of our new approach in many different applications for heterogeneous environments.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-12-05:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 20.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 20 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 6.
