Comment by periblepsis on Stable reference voltage generation
What is the charge transfer coupled from the logic control inputs? This will be a different value for on vs off, too. This will also produce an offset error. You earlier wrote in a nearly identical,...

@AlfieWren-Swords It's not entirely clear to me. In comments (not in your question, which is sad) you have said "I have built this circuit and it gives me voltage amplification around x23 but reduces...

My son is a rated expert on high speed action gaming and he absolutely does notice 4 ms delays. I need to keep the video delay down to 2 ms and the control switches and stick response times similarly...

Perhaps you may consider drawing this schematic in the existing editor that is made available when asking questions here? (I'm not even going to try reading that, as it stands.)

@AlexisKing Not "inside the wire" but on the surface of the wire. See this video for a demonstration or else the physics book "Matter & Interactions" by Chabay, et al, for additional details (which...

Mary, If you plan on using two of these next to each other, be aware that they may look like this when driven by exactly the same current. They are not intended for uncalibrated side-by-side use in...

This is the correct answer. I'm just surprised the questioner didn't notice the dipole length differences between the two.

The trade-offs are discussed in detail here. (Old Keithley app note that, since Keithley is now owned by the private company Tektronix, is found on the Tek website today. It also includes defined terms...

@cm64 Yes, that datasheet provides good information. One detail is that it is almost specified for your existing supply value. 13.2 V instead of 13.5 V, though. You don't need to drop much voltage in...

gtai, Please consider reading this paper and this paper, both from TE Connectivity. They date back to about year 2000. But useful in helping center your thoughts, today. Of course, you do need to...

Do you have a datasheet on the higher speed valve?

I think I see four tabs on it. If that's right, then likely a bridge rectifier. It does have the vague appearance of a selenium rectifier. But I have to admit that all of those I have here are bolted...

dsa, You will need to explain yourself much more fully than you have. For example, a simple wire in the air can and does receive ambient radio waves. And it can cast a shadow of sorts, in doing so....

Gaponenko, This is just a very simple, single KVL loop. Start at the lower left-hand corner and work your way around the loop. For example, \$0\:\text{V}-I\cdot 1\:\text{k}\Omega+12\:\text{V}-I\cdot...

Xenon flashlamps can be triggered quite precisely and with far, far less delay than you are asking about. LEDs, same thing. Ignorant of the details of your detection system and its behavior over...

"I have instructed ATtiny13a to continuously create..." doesn't tell us anything about how. Similarly, "I use Arduino to measure duration of each pulse..." doesn't tell us anything about how. And there...

It varies by an order of magnitude within a family of devices. So there's no point specifying it in a datasheet. I believe it's not controlled for. Not directly, anyway. Measurement systems, and they...
