How to design a 555 Pulse Width Modulator (electronic circuit)?
You can easily design the 555 Pulse Width Modulator circuit by practicing the exercises given below. Here you can design and simulate your own electronic circuits with this Online Circuit Designer and Simulator.
This circuit encodes a voltage with pulse-width modulation using a 555 timer chip. The width of the output pulses varies depending on a control voltage.
The width of the pulses is set by a triangle wave oscillator connected to the "ctl" input of the 555. The rest of the circuit is just like the square wave oscillator. By applying a voltage to the "ctl" input (normally 2/3 Vin), we can control the voltage which ends a timing interval. When the "th" input reaches this value, the output goes low. So the 555 will oscillate faster when the ctl input is lower.
