You have a 24 VAC RMS supply that is capable of providing up to 2 Amps RMS. There will be a load that is powered by the supply. If the load impedance or resistance is less than 120 Ohms, then the load will draw more than 0.2 A RMS. Are you wanting to limit the load current to be less than or...
If all you need is a 3.3V reference voltage, you might want to look at something like a TL431, a widely-used voltage reference IC. You can set the output voltage by adding two resistors.
You need to post a photo of your circuit, and also your circuit's exact schematic.
There are many things that could be done wrong, even if we assume that your code is perfect. Without a photo, it would take many, many questions to try to extract the necessary information that you have omitted...
How about the Molex-type connectors that are used for computer power supplies? Or, look at Faston-type connectors.
Whatever you do, it would be a good idea to keep the pair or triplet of wires tightly twisted together, so there is no enclosed loop area between them.
Are you simulating antennas? I have never used hfss but those sound like the components of the gain for azimuth and elevation angles.
Maybe this thread will give some enlightenment:

Also, go to the following link and enter "theta phi hfss" and search...
Here is another circuit that will do what you need.
Also attached is the LT-Spice ".asc" schematic file.
To run the simulation, remove the ".txt" from the filename,
and run with LT-Spice, which is a free download from https://www.linear.com .
I also attached a plot of the output for very...
OK. There are some physical circumstances where it would make a lot of sense to harvest RF energy. Off the top of my head, the best one might be near powerful RF broadcast antennas, basically as part of the broadcast facility. They might want to harvest the RF from areas that are not in the...
That is a restriction, for discrete-time periodic signals, probably because a period has to both start and end at a sampling instant. Continuous-time periodic signals should be able to have any frequency. Indeed, give me any "segment" or snippet of continuous-time signal, of any finite time in...
Ripple current rating is probably mostly about not overheating the cap, due to equivalent series resistance (ESR) and the associated i-squared x R losses in the cap.
So since the ESR varies with frequency, you would probably want to determine what the ESR would be for each of the two (or more)...
Presumably, you will have some source of a small AC voltage, from which to harvest energy. It could be radio waves from the air, or the output of a vibration transducer, or something else.
You will need to rectify it, so that it is all of one polarity, in order to be able to charge a battery...
Try putting about 1 pF in parallel with R2. You can adjust the value for suitability. You almost always need to low-pass filter an op amp input, so that the input slew rate can't exceed the amp's capability. In simulations, you should also always adjust the input source's rise time to be...
If you can assume that there is audio signal above some amplitude whenever it's not muted, then you can do it fairly easily, with an envelope detector and a comparator, depending on what you need as your output.
An envelope detector can be as simple as a series diode followed by a parallel RC...
Can you change the mesh size? A larger mesh would have fewer cells. They should only need to be 1/10th of a wavelength, or not a whole lot smaller than that.
