Usually, the single stable circuit outputs the solid pulse width. See as the figure, the circuit adopts the output pulse, after the pulse is low-pass filtered and DC amplified, the closed loop controls the 555 control terminal, the contemporary stable width will shrink automatically, so the cycle duty of the output waveform remains the same.
