A feed-forward control loop circuit, almost-binary counter and ring oscillator, comprising: an oscillation source; a reference frequency source having a second frequency independently generated from the oscillation source; a measurement circuit responsive to the reference source and the oscillation source; a first circuit accepting an input frequency and creating an output frequency dependent on another input; and a second circuit operating on an output of the measurement circuit and receiving a frequency input. The feed-forward control loop produces an output from the first circuit, the reference source and the frequency input being sufficient to determine the output of the feed-forward control loop.
