Abstract: Disclosed herein is a feed-forward ring oscillator. The feed-forward ring oscillator includes a plurality of delay cells for receiving a first differential input signal pair and a second differential input signal pair, and outputting a differential output signal pair. The delay cells are connected in a ring shape. Each of the delay cells receives a differential output signal pair of a delay cell of a previous stage as a first differential input signal pair and receives a differential output signal pair of a delay cell of a stage before the previous stage as a second differential input signal pair. Each of the delay cells comprises multiple independent gate field-effect transistors.
