ABSTRACT:
A ring oscillator includes a plurality of inverting delay elements connected in a ring. Each inverting delay element includes an inverter having an output node. The oscillator also includes a programmable current circuit operable to rob a variable amount of current from the output node of the inverter to control the duration of a delay period associated with the delay element.
