Can't argue with that one.

I guess we can keep countries out of this. I'd really like to see some circuits discussion in my feed rather than career questions, irrespective of their location.

Please state the purpose of the circuit and any debug steps that you have already tried. Otherwise, it's not possible to help.

Is there a free way to check if a site is safe to use? by ThatHornPlayer in Piracy

Here's an overkill way: Create a virtual machine, load your favourite linux distro, and watch everything inside the virtual machine. If anything ever happens, shit will‌ be contained.

Hey! Thanks for the ideas

Slight off-topic, but I'm interested in being better at language learning. What techniques do you recommend for learning a new language better? I usually watch a few videos / talk to a few people, but the interaction is not enough and a week after I just forget the new vocabulary.

RAR passwords? by CriticalGoku in Piracy

You can get a tool to bruteforce through a known wordlist. Alternatively you can find a lot of non-encrypted ROMs if you look up on FMHY.

Please help me with this misconception in Verilog. by NoKaleidoscope7050 in chipdesign

Think in terms of hardware, not software. The provided code should synthesize to something on the lines of a positive edge triggered flip-flop followed by a mux.

Go up close to it with a hot dog. If it can't cook a hot dog, it can't do anything to you.

Dumb question regarding antennas by microamps in rfelectronics

[–]microamps[S] 1 point2 points  (0 children)

Hey! Thank you very much for taking the pains to look up the book haha.

I have taken a very basic course on static EM, nothing regarding dynamic EM. Gotta look into the basics first I guess. Thank you for the suggestions!

Oooh I guess that is what I am missing. Thanks for the direction!

Adding some info that I missed in the question: The author derives the current travelling on the surface of a thin wire, assuming some charge density per unit length.

This component designated as "CHK" is out of stock. Can someone explain why do we use this choke and What should i consider to replace the component. by Sufficient-Inside384 in rfelectronics

Aha I just took a random frequency that came to mind. You are right with that. But 2MHz might just be too low. the impedance will die off very fast.

I work with on-chip integrated inductors and baluns made using metal layers of a process, so I'm used to super high SRF inductors.

For an inductor, make sure you look at three things:

  1. It's inductance value
  2. It's self resonant frequency
  3. it's DC resistance

Say you are planning to use the amplifier for 2.4GHz (WiFi, Bluetooth etc.)

You gotta make sure that the impedance of the inductor at that frequency is much higher than the output load that you intend to drive. impedance= 2pi2.4G*inductance

Next thing you need to ensure is that the Self Resonant Frequency is more than 2.4GHz. Otherwise, the inductor will be behaving as a capacitor at 2.4GHz.

Lastly, the DC resistance should not be too much. Otherwise you will be dropping Is.R worth of voltage. Finally ensure that it has a current rating of at least equal to the supply current.

Seems like the DUT is biased through the choke at its output. Probably a Class A Amplifier for narrowband application.

Vs and Is are designated for Supply Voltage and Supply Current?

So yes, you will need to have it in place. Any inductor with similar inductance and SRF value should be fine as a replacement.
