SI5351 PROTEUS LIBRARY HOW TO

I have wanted to learn about embedded USB devices so I ripped off the bandaid and forced myself to learn how to make one by giving this board no other connectivity. I'm not sure if this is appropriate as a new log entry on the old SNA project or if it should be its own new project as it's undergone some pretty drastic changes! So a bit about the new design. Zip Archive - Adobe Portable Document Format - This project has been silent for quite a while now but it is not due to lack of interest. I could fix it by putting a state machine into the program, but it works pretty well as is so I haven't done that yet. It has a known error where sometimes when decreasing the number of samples in a sweep, it throws an index out of array bounds error and stops working. I also screwed up the DC biasing Oh well, that's why I made Rev 2! I wrote a program to display the trace and control the board in Python. Rev 1 had many issues, the worst of which was the amplifier on the output. This was a great way to get my feet wet and learn many things about building circuit boards for RF work. How do I know if I had a good one? I could use the Spec An itself to tell me or I could make a simpler piece of test kit this Network Analyzer shield that would help out in building all manner of RF things.

It would cover DC to daylight and be everything I'd ever wanted But I decided to start smaller.

I have the idea of building a Spectrum Analyzer with a dual conversion superheterodyne architecture. As an electrical engineer, I love test kit. We found and based on your interests.Д¬hoose more interests. To make the experience fit your profile, pick a username and tell us what interests you.

This will produce a seesawing potential pushing and pulling the current through the body.Not a member? You should Sign Up. This is a so-called Load-in-the-Loop setup. After the current sensing resister there is an op-amp in a negative feedback configuration. We use the excitation voltage from the AD and the max current value. Using Ohms Law on the resistor we can calculate the resistor value that will comply with the safety standard. At frequencies above 1kHz the following equation gives the maximum allowed current. The current through this resistor will be the same current that the amplifier will try to maintain through the body. The first part of the next stage is the current sensing resistor. This is to make sure that the resistor values do not interfere with the next stage. The last part of this stage is an op-amp set up to be a voltage follower. If you plan on using 1kHz in your application you should go for caps and resistor values that will give you a cutoff frequency on the order of Hz. Make sure that the cutoff frequency is a few decades below the minimum frequency you plan on using. The specific value af the cap is also not important. The two re-bias resistors can be any value as long as they are the same. This is corrected by using a capacitor to block the DC part of the signal and sending it through a voltage splitter to add a DC offset back into the signal. The first part of the AFE is a re-bias stage.

If you plan on using the Arduino as a power supply make sure that the operational and instrumentation amplifiers op-amps and in-amps support so-called 'single supply' voltages and have rail-to-rail specs.Дid you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The AD then does the measuring and the results can then be processed by a microcontroller e. If you think you can write this up and improve, you are welcome. I might someday write my thought up in a more cohesive form, but for now I hope you can use whatever you see here. Take what you can use from this 'walk-through' if something isn't clear please suggest improvements. I would like to share my findings with you. I have worked through the design and improved it slightly. I have been interested in making a Bio Impedance Analyser for body composition measurements and my random searches kept finding a design from the Biomedical Instrumentation class at Vanderbilt University. Simple mini projects for mechanical engineering students.
