Producing Ramp Voltage Using Simulation: What You Need to Know

[Cooler]

hi,

does anyone know how to produce ramp voltage using simulation? what components or circuits i need to use?

thanks, helps really appreciated.

You can use an integrator feeded by a step voltage.

LT Spice allows you to put a voltage generator into the circuit and then use DC Sweep mode to produce a graph with this voltage along the bottom. You then click on other points in the circuit to get the resulting trace for that point.

To set it up, you just have to tell it two voltages you want to sweep between and an increment to give the size steps you want.
