Abstract
A ring oscillator is disclosed according to certain aspects of the present disclosure. The ring oscillator include N flip-flops, each of the N flip-flops having a data input, a clock input, and an output, wherein N is an integer greater than 1. In certain aspects, the output of each of the N flip-flops is coupled to the clock input of an adjacent other one of the N flip-flops, the output of each of the N flip-flops is coupled to a reset input or a preset input of a non-adjacent other one of the N flip-flops, and the data input of each of the N flip-flops is coupled to a voltage line or a ground line.
