The help DOES tell. Look for Chan Model; that will get you close. Jim Wagner

That DOES NOT work, just like it does not work for caps. Jim Wagner

You run into the same issue as time varying capacitance; you cannot just change inductance with time. How to handle it is in Help, though very obscure. I thought that I had seen it in an older version

To amplify this slightly, a PLL loop is DESIGNED to drive the frequency difference AND the phase difference between the two signals to zero. With that design goal, there cannot be a DC frequency diffe

Drift in the feedback voltage of a PLL usually means that the VCO has poor stability. For example, this WILL happen if the VCO frequency is controlled by a varactor diode (varactor diodes have a subst

Not much to explain. Pulse Width varies the width (an equivalent name is duty cycle) with the external signal, leaving the period constant. Period varies the period of the square wave, leaving the pul

Or amplitude?

Modulate period or modulate pulse width? Jim

I would argue that the relay model is a "nothing", derived with a fair amount of accuracy, from the voltage-controlled switch. The antenna, now, THAT is a really big challenge. A resistor is, at best,

Thanks, Andy. When I wrote that, my mind was still in the frame of "making a constant power load". I do appreciate the details, anyway, because I have stumbled over them a few times. Jim

Thanks, Tony Jim

Thanks! I thought behavioral sources did not allow instantaneous feedback. Jim

Greetings - I would like to create a generic constant power load to mimic a SMPS effect on a network with diodes, capacitors, supercaps, and such. It would really be cool if limiting behavior of the l

You need to ask the EDA support people or forum pr "community". LTspice has nothing to do with the layout process for the board. Jim

Is the input signal near the center of the amplifier's specified input common mode range? Jim

On your question about Im(V(out)), I think about it this way. In the case of simple RLC circuits, the output voltage is a sine (at the same frequency as the input) that has a different amplitude (usua

Sorry, Marcel - I left out some information without realizing it. I am using LTspice XVII for MacOS. The Help index shows nothing about Waveform Arithmetic and I was concerned that Waveform Arithmetic
