Abstract :
A high-speed ring oscillator is proposed for improved operation frequency over those based on the conventional n-stage inverter chain. The ring oscillator consists of inverters with negative delay elements that are derived from the ring oscillator circuit. The cell delay of the ring oscillator is smaller than a fundamental inverter delay. Simulations show that the resulting operating frequencies are 50% higher than those obtainable from the conventional approaches
