RING OSCILLATOR HAVING WIDE FREQUENCY RANGE |
摘要 |
Provided is a ring oscillator having an extended range of oscillation frequency by varactors coupled to delay cells even in a simple structure. The wide frequency range results from simply varying an oscillation frequency by control signals applied to the varactors. Since additional switches connected to the delay cells contribute to increase or decrease of the oscillation frequency range, the ring oscillator can conveniently be employed in various types of oscillation systems.
