When a pulse transmits through delay stages, it dies out after all unless the rising and falling delays are perfectly matched. Alternatively, an edge can be transmitted through the new generateand-reset delay stages if properly reset in time. A new delay-based clock generator adopting the delay stages is proposed on that account. It is attractive in that the maximum operating frequency can be comparable to that of the ring oscillator. Furthermore, the reset of the pulse in the delay stage
