Frequency Synthesis Using a Ring Oscillator |
摘要 |
The present disclosure is directed to a method and apparatus for providing an output oscillating signal at a desired frequency. In at least one example, the apparatus includes a weak inversion structure configured to set a small reference current. A current mirror configured to provide a replica current based on the small reference current and a tuning word. A ring oscillator is configured to be powered by a supply at a voltage determined based on the replica current. The tuning word is adjustable to change the voltage such that the ring oscillator provides the output oscillating signal at the desired frequency. |
