Abstract: A ring oscillator with an overstress solution is shown, which includes a plurality of oscillation units connected in a ring, and two capacitors. The first capacitor has a first terminal and a second terminal that are respectively coupled to a first node and a second node of the ring. The second node is an input terminal of a first-stage oscillation unit. The first node is an output terminal of a later-stage oscillation unit. The first signal at the first node is generated by inverting an input signal coupled to the input terminal of the first-stage oscillation unit an even number of times. The second capacitor is coupled between the second node and the ground terminal.
