Abstract
Several ring oscillator constructions are provided. The ring oscillator includes a plurality of logic gates connected in a ring configuration. An output of each except a last of the plurality of logic gates is used as an input for a next one of the plurality of logic gates. The output of the last of the plurality of logic gates is fed back to and used as an input for a first of the plurality of logic gates. A logic gate of the plurality of logic gates includes an enable input to receive an enable signal to enable the logic gate and thereby the ring oscillator. The plurality of logic gates includes at least one controlled logic gate that also includes a clock input to receive a clock signal to control the at least one controlled logic gate and thereby synchronize the ring oscillator to the clock signal.
