From an input signal, and using an unusual current source, this circuit generates a ramp, that is, a voltage that grows linearly up to a certain value, and then falls.
We found this circuit in an Analog Devices documentation from the 90s. The circuit is based on a...
This circuit turns off a load after an interval of 8 to 80 seconds adjusted on the potentiometer. The...
