Programmable/Stoppable Oscillator Based on Self-Timed Rings
Résumé
In this paper a Programmable/Stoppable oscillator is designed based on a Self-Timed Ring. A new model is proposed to calculate the oscillation frequency of the ring. Different solutions for introducing programmability to self timed rings are designed and implemented. Using different techniques, the implemented oscillator achieves a frequency range of 3GHz down to 400MHz with a smallest step of 100MHz.
