Hello.
I am not a specialist in high speed digital electronics and I am trying to build an RCL measuring circuit for high-impedance RCL circuit analysis.
I would like to use a demo board of atmega328P - arduino sounds like a good fit.
I want to excite the RCL with a short pulse and measure the frequency, than excite the RCL again, carefully positioning the impulse in time so I am not causing a frequency change or a phase shift in my RCL circuit.
The illustration shows the basic architecture. The project I am building will be open-source.
I want to choose the 2 voltage dividers and a buffer (if I am connecting Arduino synchronously( or 2 buffers and a voltage divider (if I am connecting it asynchronously).
This should run at 100MHz to 1GHz and I will have to develop the PCB so it works without mistakes.
I would like to have a voltage divider that will tell me the frequency of the RCL between the input pulses from the buffer and a voltage divider that will tell me the average self-frequency.
If I want to run Atmega synchronously, I will need a clock divider to run it off a 100MHz to 1Ghz clock. If I wire it asynchronously, I will need to use a buffer so it puts in a value of when the pulse event has to occur in time and the time it has to happen at.
I am not sure what ICs I can use for this task. My test RCL circuits (antennas) are designed for the frequencies of 100KHz to 1 MHz. I will need a higher resolution to place the excitation impulse in time correctly.
What ICs should I choose to solve this problem? What is the most optimized solution for my task.
