Assuming we have a voltage regulator : Why do we have to ground Vin and Vout using 2 capacitors just like that?Co could be to provide a low resistance path to GND at high frequencies but what is...
I must admit that your question (the described problem) is an interesting one. Speaking about the circuit (without consideration of the parts values), there are two feedback effects: At first, ...
There is a mistake in the last line: $$\eqalign{V_{C_1}(t) &= V_1(t) - RI_{C_1}(t) \cr &= \sin(t) - \dfrac{\sin(t) + \cos(t) - \mathrm{e}^{-t}}{2} \cr &= \dfrac{\sin(t) - \cos(t) + \m...
Is this equation valid only when a JFET in saturation mode , correct? because in the ohmic region the JFET acts like a voltage controlled resistor and increase in VDS increases the resistance of th...
I am not familiar with that chip, and only took a very quick look at the datasheet. Here is the block diagram of the part from the top of the first page: A few things pop out from this: This c...
The RSSI detector in the receiver is the best field tool. In Windows I had a tool (Wifi Radar?) that read the Broadcom IC RSSI and displayed a time plot of the results as I changed laptop orientati...
How can we find the equation of current and voltage of a capacitor circuit if the input voltage is AC without using the impedance formula Xc = -jωC?. We have for homework to find the equation of...
I have been trying to model this oscillator I was wondering if we can somehow predict the frequency of the oscillations.For small currents inside a diode from the Shockley diode equation $$ e^{x...
At Somewhere Else, we started an initiative to make a community-maintained list of abbreviations used in electrical engineering: What are abbreviations used in electrical engineering? I think it c...
This LC circuit depends on several criteria for stable linear oscillation; 180 deg phase shift ( with 3rd order LC network) plus 180 degree inversion to achieve the oscillation criteria of 0 or ...
If you mean electret microphone, no damage to JFET buffer. Microphone input won't damage a headset with it's current limited pullup resistor for electret Mics.
I think you are over complicating your thinking a little bit. For an associated device the only thing that matters is how you limit the energy going into the hazardous area. You put your zener barr...
I'm thinking out loud here and haven't solved this yet. This answer is logging my process as I try to solve the problem. It may very well result in the same long-winded process you went thru. No...
If we have the transfer function of a LC high pass filter: $H(s) = \frac{sL}{sL+\frac{1}{sC}}$ If we want to find the pole of that filter in the end we get: $s = \frac{j}{\sqrt{LC}}$ and for a ...
I am trying to find the AC analysis of a BJT Hartley oscillator but I cannot continue. How do I find the voltage gain? When no feedback is there, we just find the output resistance and the current...
Easy way to convert over long comment into an answer. It would be great if while typing a quick comment to a question you realise that you are about to exceed the character count and it is a valid...
you want a current source start with a linear regulkator like LM340 and use the relays to switch in different load resistors.
CATV distribution is typically half-inch rigid coax, so it's not that. It looks more like a fibre junction box "aerial fibre terminal" in the parlance.
Load line Formal "explanation" In common emitter collector we just draw a line from the vertical axis (Ic) at the point (0,VCC/RC) to the horizontal axis at the point(VCC,0) and where that line...
I would like to convert 5V rail I have on PCB to ±12V. Existing solution is using boost converter 5V to 12V, and a buck for 5V to -12V. This feels bulky for what it's needed - here are the requirem...
As of the early 2020s, common technology nodes for SSI (Small-Scale Integration) and MSI (Medium-Scale Integration) ICs include nodes such as 180nm, 130nm, 90nm, 65nm, 45nm, and 28nm. Each technolo...
CAN lines in the most common implementation have 60 Ω impedance between them. Anything that is substantially larger than that won't effect the lines much. I'd use 1 kΩ at least, preferably more. ...
Long-standing bugs ought to be fixed. I got another "500 server error" on an edit suggestion (this is far from the first time): 500 server error It's not your fault. This error has been logg...
I agree with Olin that unknown contact area is the biggest variable. I think the scientific way is to test and verify each contact using a 4 pin kelvin bridge. The sum of 2 pins carrying constant...
