I need to design a simple boost converter like this: - I want to control duty cycle from another circuit such as an MCU but, I'm unsure how to proceed. My requirements are: - Input voltage 12 vol...
Low-pass impedance transformation Theory Input Impedance: - $$Z_{IN} = j\omega L + \dfrac{\dfrac{R_L}{j\omega C}}{R_L + \dfrac{1}{j\omega C}} = j\omega L +\dfrac{R_L}{1 + j\omega R_L C} = \dfrac{j...
I have a signal at 10 MHz produced from a 50 Ω source. How can I match that to a 300 Ω load with low losses without using an RF transformer (space constraints)? Are there any circuits and formulas ...
How can I acquire electronic parts/items/modules and ensure that there is minimal risk of them being unsuitable for my project or design?
What is the relationship between the pole zero diagram and bode plot? Case example: a 2nd order RLC low pass filter: - $$\dfrac{V_{OUT}}{V_{IN}} = \dfrac{\frac{1}{j\omega C}}{R+j\omega L +\frac{1}...
The line at the top of the list of Questions is currently: General Q&A about the design and function of electronic and electric power systems, their theory, and tools specific to those fields. ...
Personally I'd rather have everyone use their real name and affiliation. That basically puts their reputation out there on anything they say. If you really believe in something, have the guts to ...
I am really confused how the terms bit-rate are baud-rate are used in electronics. I never bothered thinking about baud-rate being different than bit-rate before. But recently, one of my teachers t...
It could be OK if you are asking about technology reasons why a class of products will be phased out. Asking about forces that cause similar things in the past should be OK too, as long as the rea...
How to test a Tunnel diode in 25 words or less. With DC bias = ~490mV with fine tuning and a small signal swing of 60mV you can generate a IV negative slope of -16 Ohms.
Would a question about cabling repair be on-topic? My main focus would be to learn about the proper workmanship to do a professional, not just makeshift, repair on an automotive sensor cable.
... it is still unclear to me how to determine the voltage drop introduced by these transistors... Very interesting question... I have asked myself many times in the past... and I have not bee...
Not a diff amp Something doesn't make sense here. You want A1A to act as a differential amplifier, but that's not how you wired it: Here is a real diff amp: Note how the right side of R1 is...
I thought I understood the theory of scattering parameters, smith charts etc. until I tried a practical example. The following stupid example is supposed to be a microstrip line shunted by two 100...
In addition to Olin's answer: and I'm particularly interested in jfets and mosfets. If you decide to go down the FET route the dilemma between J and MOS gets down to home much you are willi...
In addition to what Lundin said, making ACK dominant means that something out there is actively responding, and that response is affirmative. If ACK were recessive, then the transmitting node bein...
In the absence of VNA product documentation...... Now, -9 dB is equivalent to a ratio of 0.34 approximately, and -3.53 db is equivalent to a ratio of 0.66 approximately. I expected S11 to be nea...
Here's the thing, and this is where I think there's a disconnect of understanding. On Stack Exchange, and to a similar extent here, question closure signals "this question is not suitable for this ...
I am trying to understand tunnel diodes by experimenting with them. Research tells me they can have negative resistance, and can be used to build a high frequency oscillator. Tunnel diodes are su...
As I understand it, microwave oven magnetrons operate at 2.45GHz, which is an unlicensed band in most of the world. When 2.4GHz technologies such as WiFi (802.11), Bluetooth and Zigbee were launche...
Is it possible to add the name of the OP near each question inside the question list? Only the name of the "last activity" person appears there. For me, that would help. I would like to see somet...
Here is another "functional explanation" of this phenomenon (see also my RG question). General feature. Unlike resistors that directly decrease current, both capacitors and inductors do it by subt...
All good designs and design testing is based on information contained in the component data sheets. A solar panel is no different so, you need to establish the operating conditions for measuring vo...
Hello I don't understand how this differential to single-ended voltage converter can work. What I don't understand is why we place a current mirror(a current mirror copies the current flowing thr...
What you describe is already allowed in Papers. See electrical.codidact.com/help/papers. The papers by Circuit Fantasist are well on topic. Presenting a concept in an accessible way is OK. I ha...
