Abstract:
1. A method comprising: determining a frequency of an oscillator signal communicated from a ring oscillator to an inverter along a first communication path, the first communication path being divided into a second communication path and a third communication path, the second communication path having connectivity to a first voltage source, a first ground path and the inverter, the third communication path having connectivity to the first voltage source, the first ground path and the inverter; generating a non-overlapping clock signal to facilitate communicating the oscillator signal along the third communication path and an out-of-phase signal along the second communication path, wherein generation of the out-of-phase signal is independent of the signal communicated along the third communication path; determining a first current associated with the third communication path; and determining an effective capacitance of the ring oscillator based on a first voltage of the first voltage source, the first current and the frequency of the oscillator signal communicated to the inverter along the third communication path.
