of course you are.
The GND plate was isolated from the rest so I needed to insert some vias.
actually that was total obvious .. I failed this morning... :drevil:
Hi guys,
i've a problem...
Eagle still shows me an airline(ripup-line) although it's connected by the GND-Layer and the Pads.
I did Ratsnest a couple of times, I tried a new GND-Polygon and I also checked the Schematics.. everything fine..
- How can I solve that?
- And by the way...
Hi there,
I designed a circuit for a measurement-task.
230VAC will be transformed into ± 12VDC (normal procedure.. transformer-> bridge rectifier -> 78XX/79XX. Of course there are some filter to eliminate noise.
After voltage regulation, the ± 12VDC will supply an operation amplifier which...
dammit! sorry but I am really upset about myself for being so distracted with the schematic.
makes sense with the highpass filter..
I worry cause I want to use that setup for measurement..
the input is green - output is yellow.
I will change my circuit and correct the mistake with the (+) and...
the present question was... if it's a good idea to try these two layouts?? but I already did..
the first circuit was great but I had to add a 5pF capacitor in serie to the output (if not so there will be a dc-offset).
Like so, I have a good result but also a drift from the generated...
Hi,
I found an old thread here.
For the MOSCap

Sorry that I couldn't help you with the IPD's (only found something on wikipedia but I think you already read that)
so thats why you became so rich and that guru at the end Audioguru :-P
Little joke you know...
but alright.
I will try to built two circuits.
The first will be the circuit from the AD datasheet with G=+1 and in this case it's an impedance follower right?
The second will be the impedance...
The Ground from the scope and the signal source are the same... but actually as you said.. there are connection in form of wire which has a length of 10-15 cm (average)..
So after reading your replies I think that I'm really getting these sort of loop antenna.
Do you think it's possible to...
Well... sorry that I didnt show that in the schematics... That was my fault! Of course the connection of +/- 12 VDC is connected and also the connection to ground.
I made the schematics very fast and so I forgot to draw that.
So lets assume that the connection of Source and the clearing of the...
Hi guys...
I tried to build up an impedance converter with the AD8065 on a breadboard.
After seeing that there are a lot of problems due to distortion and noise I made some screens with the scope..
Here is the last circuit I built and the screens from the scope/ the waveform generator...
right now I only have this information about the rf-generator which generates the signals
Source of the rf-generator 100 - 120 V, 50/60 Hz, 12 A
The generated signals: it depends on which settings.. so about 0 - 600 W, 900 V, Resistance of 0 - 2 kOhm
I know that the voltage in the electrolytic...
