Abstract
A ring oscillator includes an oscillation module, a first delay module, and a second delay module. The oscillation module is disposed in a first delay loop and a second delay loop and includes a first number of latches connected in series. The oscillation module has two input ends and two output ends, and the two input ends are respectively connected to a first node and a second node. The first delay module is disposed in the first delay loop and has an input end connected to a first output end of the oscillation module and an output end connected to the first node. The second delay module is disposed in the second delay loop and has an input end connected to a second output end of the oscillation module and an output end connected to the second node.
