Abstract
This paper details the design and implementation of a new type of semiconductor parametric ring oscillator used to predict the speed of a device. The new oscillator, " A Critical Path Based Parametric Ring Oscillator," represents the actual critical path of a device. The concept behind the critical path based oscillator, along with the design and development process, are presented. The oscillator was implemented in a complex microprocessor using an advanced CMOS process. Using the new oscillator, the speed of a device can be modeled more accurately, thus leading to better material planning and also improvements to yield analysis.
