Hey,
just came across a link on DIYaudio forums about the sudbury neutrino detector preamplifiers... Apparently, they are super-low noise (<<0.3nV/sqrt(Hz) and <<1fA/sqrt(Hz)) but the funny thing is the report was open access 5 years ago; not so anymore! Cant even find any literature describing...
Hey everybody,
Guess I am asking questions that are too mundane for this forum. Anyways, the story is I figured that this weird notation has something to do with MWOs internal ideas of Node voltages. The devices do seem to work fine regardless. I guess it is too much of an ask to get people to...
I hope some help is still around! I'm uploading the .emp file (in a zip file because edaboard uploader doesn't seem to recognise .emp). As I've said earlier, any advice is useful.
Hey manju,
As far as biasing goes, I have just followed the standard connections specified in the OPA657 datasheet; +-5 volts supply to respective pins with decoupling capacitors. As this is an OPAMP I wasn't aware of the need for biasing. Wouldn't the SPICE model behave analogous to the...
I'm trying to design a transimpedance amplifier to work from about 300kHz to 100 MHz, using the OPA657 from TI. A side project was to learn MWO, which I have never used. I tried to do a voltage annotation for all the nodes and don't quite like what I see... I should clarify that the OPA657...
