Ramp Generator Using 555 Timer. When the capacitor has reached 2 3 supply voltage the 555 timer switches to discharge mode and discharges the capacitor to a level of 1 3 supply voltage almost immediately. The post explains how a ic 555 timer ramp generator circuit can be made using a single ic 555 and few other passive components.
The current ic from the constant current source will charge the capacitor at a constant rate towards the peak voltage vcc resulting in a rising linear ramp. This constant current source is positioned in place of the timing resistor. This allows the capacitor to charge through a 47 kω resistor.
