In the figure is the simple pulse frequency doubler. This circuit is a simple pulse frequency doubler whose output pulse width depends on the time constant RC. By the figured element value, the output pulse width is 1/4 of the input pulse period. To different types of integrated circuit, the values of R and C are different. If the two same circuits are connected in the serial way, a 4-time frequency doubler circuit is formed, but the the second stage time constant RC is 1/2 of the former one.
