A voltage reduction technique for battery-operated systems
... ratio of the delay of a critical path to the period of a ring oscillator is a constant which depends only on the number of stages, the dimensions of the transistors, and the load capacitances. That means that a ring oscillator can be used as an equivalent critical path for all digital circuits. Sinc ...
