Good free simulator for dc sweep

I need to do a DC sweep of a circuit involving a NMOS, but my version of Multisim doesn't have that option. Which free simulator would you recommend for a DC sweep?

Can an electronic device continuously sweep the voltage?

Modern power supplies can sweep the potential in a given range with a specific rate. I am curious if the electronic devices can continuously sweep the voltage (in a perfect sense) or it is just step-based changes, which seem like sweeping? For…

Combine DC sweep with time analysis?

I am working on LTSpice on a project which consists in transferring energy from a PV panel to a load through a transformer, using a controlled bridge at the primary and a diode rectifier at the secondary side of the transformer. I am trying to…

Using .MEASURE on DC sweeps in LTspice

How can I .MEASURE at what input voltage a certain current occurs when doing a DC sweep in LTSpice? For instance, consider the following situation: I was hoping to find the voltage that generates a base current of \$200\mu\text{A}\$ by using FIND…

NPN circuit (breadboard)

What does this NPN BJT circuit represent, is it a switch or just a PN diode, and what should this plot look like when we sweep the value of Vbe, and why?

Is it possible for any circuit to independently make its own trigger, sweep or oscillation without the aid of an AC sine wave?

Even a Schmidt trigger, attributed to being able to create the start of an oscillating circuit, has to get its start from an AC sine wave. It seems that no amount of tubes or transistors can independently make their own trigger. This mechanism for…

If a sweep generator gets up to 20 GHz, Is it possible they only mean pulsed DC rather than AC?

I'm looking at a Wavetek model 8911 10 MHz-20 GHz Programmable Sweep Generator, It says it gets up to 20 gigahertz, but is it possible that it only generates pulsed DC at that frequency as an excuse to say it gets "20 GHz" It's quite expensive and…
