Re: beginner would like to design a circuit
Hi Brad,
He can generate voltage linear ramps by charging/discharging a capacitor using a constant current source.
Zeyad, what kind of load do you have in mind? I find quite hard to imagine the utility of such a circuit.
You could do this using a microcontroller (provide the timing), a DAC (controlled by the microcontroller to approximate the ramps by small steps) and a voltage controlled current source from 0 to 50mA, but it's not an easy design for a beginner.
