The video helped explain a few things, but it's still not clear what the overall purpose of this device is. You showed it clearly producing a signal, but the documentation you quote talks about an...
What would be the main considerations to use Pi-filters for EMC?
I recommend using native HTML for lists, and most other formatting for that matter. HTML gets around the ambiguity of what is an item and what is text following the list. The list isn't over unti...
Why does the Darlington or Sziklai configurations need complementary transistors? For these configurations, when should I use complementary pairs and when could I use not complementary pairs ?
let me begin with a schematic for an adjustable current source with a simple load: The operation is simple: The current I inside R1 gives rise a voltage drop equal to I/R1 (= I if R1 = 1). So the ...
Assuming nothing is broken or wired incorrectly, this is most likely the result of the opamp oscillating wildly. The average may still be about what it should be, so you might not notice with only...
RTOS A RTOS (Real Time Operating System) is much more than a bunch of interrupts. Most true dedicated microcontroller applications don't need any RTOS or any other kind of operating system. Genera...
Well, here is was my logic tells me: The corrosion has caused a high impedance in the L2 wire, but there should be also a "short" between the L1 and L2 wire. So that the voltage between L1 and L2 f...
My step-up converter makes audible noise both with and without a load.I am almost certain it is the inductor, because when I hold my finger on it I can feel vibration and it gets quieter. Unfortuna...
It doesn't quite work that way. You are missing the fact that the current (which the magnetic field is proportional to) decays exponentially. You are also missing the resistance of the coil itsel...
When the outage occurred, I observed the following The L1/G voltage difference was 120V (good). The G/L2 voltage difference was 90V (bad). The L1/L2 voltage difference was 30V (very bad!). If t...
Hello, I am designing 1/4 WL strip antenna for a bluetooth chip and i had some questions regarding the 50 Ohm feed line. Right now I am using a Nordic-recommended 1.5mm trace width and a 23mm + 4mm...
Despite there are many filter calculators available on the web, I still have difficulties to translate what I need into calculator design parameters. For my application, I need ideally a high pass ...
A voltage source is "heavily loaded" when something is drawing a large amount of current from it. "Large" in this context is relative to what the voltage source can deliver, or perhaps relative to...
Consider this statement "A voltage source is heavily loaded",what does this mean? I mean that whether the load resistance is high or there is huge drop in source voltage at load due to internal res...
I am having a difficult time picturing the flow of current and the role of the capacitor during the OFF time of a buck converter. Here is my understanding so far. During the ON time the magnetic fi...
A switching power supply already is inherently a filter. Current is coming thru an inductor, followed by a capacitor to ground. If you are asking what additional is usually done to filter out chan...
There is always a mixed response when comparing power management ICs (PMIC) and microcontrollers in the application of power converters (I mean as pwm controllers). What are the advantages and dis...
These are my general thoughts: - Easiest - power management IC (PMIC) Smallest footprint - PMIC usually Cheapest - usually PMIC (for a certain minimum performance level) Highest performance - PMIC...
I'll assume by "PMIC" you mean a dedicated switching power supply chip. Such a chip contains the PWM generator and receives output voltage feedback at a minimum. They may also include a driver fo...
With the capacitor C3 disconnected, the stage has a minimum gain and with C3 connected it has a maximum gain. There is a compromise solution with a moderate gain - to connect a resistor in series t...
It's not clear what you are really asking, but here is something that might fit your requirements: First, R1 and R2 can be considered separate loads. The transistor therefore switches two loads. ...
I can think of a couple of reasons: Lower frequencies mean superior range at the same output power. Whereas for example 2.4 GHz technologies tend to behave much more "directional" on short ranges...
Any deviation from the example antenna could have significant and unintuitive consequences. Unless you have good antenna modeling software and good understanding of antenna physics (which you appa...
And to add to Olin Lathrop's answer, case 1. might be called "multidrop" or "party line" or "dot-or" connection. IIC bus as a good example of WHY we might use this case. Case 2. allows what might ...
