Title:
HYPER-RING OSCILLATOR, SYSTEM WITH THE SAME, AND RING OSCILLATING METHOD
Document Type and Number:
Japanese Patent JP2005094754
Kind Code:
A
Abstract:
To provide a ring oscillator, its method and its system capable of generating a clock signal with a high frequency.
The ring oscillator has a first logic circuit forming a first loop. The ring oscillator also has a second logic circuit forming a second loop, such that phase interpolation occurs at a node common to the first and second loops. The phase interpolation results in an output signal with a high frequency.
