Simple pulse frequency multiplier
Source: InternetPublisher:toothache Keywords: Pulse frequency multiplier Updated: 2023/12/11
The figure shows a simple pulse frequency doubling circuit. This circuit is a simple pulse frequency multiplier whose output pulse width depends on the time constant RC. Using the component values shown in the figure, the output pulse width is 1/4 of the input pulse period. The values of R and C are different for different types of integrated circuits. If two identical circuits are connected in series, a quadruple frequency circuit can be formed, but it is required that the time constant RC of the second stage should be reduced by half.
