I saw the reference design file CN0349 and CN0217, I think both are 2-wire implementation of the AD5P3x family IC. Can I get the circuit reference for the 4-wire implementation, with impedance range of 50 to 250 ohm.
Help will be highly appreciated.
You may use this post as a starting point:
In the link, it is mentioned that setting Rcal = 20 can set the impedance range from 1 to 60. Can you please explain this, I did not get this. How can Rcal resistor set the range.
With this 4-wire circuit the output is directly proportional to the impedance under test.
Yes, I missed that point. Now I am getting 109 Ω when measuring 120 Ω.
The real component is 109.5 Ohms, which is a bit far from the expected 120 Ohm, but it could still be within manufacturing tolerance of both the resistors used for calibration and as the "unknown."
I ordered more resistors (different values) I will calibrate and measure a bunch of different resistors.
Thanks once again.
This is the result.
Yes, it would be great if you could find some 0.1% or better yet 0,05% resistors. Only avoid wire wound type - those may have too much inductance for AC measurements.
I did test and calibrate using different resistor values. I noted that the measurement accuracy is better near the calibrated resistance value. I think this is not a problem, this I can improve using some tricks.
The problem now I face, is, when I use 4 wires and short 2 wires together (T1 with R1 and T2 with R2) see the picture.
In this case I can get reading. See the pictures as a reference.
4 wires, 2 wires short together.
This is the waveform in the saline water.
But, WHEN I use for wires or electrodes separated from each other, then the behavior changes completely. I can not get any proper reading. please. check the pictures below.
This is 4 wires, first (white) and last (brown) are T1 and T2. Second (Blue) and third (black) are R1 and R2 (R stands for receiver)
This is the acquire waveform,
Saline water is used in both cases, with conductivity of 7.37 mS/cm.
Can you help with this.
Thanks
wires or electrodes separated from each other
I am not sure it is possible to separate the excitation wire Tn from the corresponding sensing wire Rn when in saline - it is going to break the DC working point of your circuit. Roughly speaking, the wires in saline are not galvanically connected to each other due to polarization layer forming at the interface. Very crudely, you can think of it as a capacitor between the wire surface and bulk saline, so the equivalent circuit approximating corresponding behavior would be something like this:
So, the sensing side of your circuit does not have any DC coupling to the rest of the circuit and your INAMP inputs are hanging at whatever voltage these capacitors are charged to by the input pin currents and leakages. On the excitation side this polarization "capacitance" would break the DC feedback loop for U2, that is why some kind of R11 is necessary.
I will add a capacitor on each Rn wires. This might block DC values.
The point is that, once wires are disconnected and put into the saline, the DC voltages are blocked by the equivalent capacitance of the polarization layer between the wire and electrolyte. Adding capacitors will put those in sequence with the polarization layer and will not help with the DC bias of the INAMP - the inputs would need to be DC-biased by some additional circuits. Connecting T1 to R1 and T2 to R2 takes care of the DC bias automatically, why would it be necessary to keep those wires apart?
the DC voltages are blocked by the equivalent capacitance of the polarization layer between the wire and electrolyte.
Got it,
But, I just went through the following link.
https://www.instructables.com/Body-Composition-using-BIA/
I did not found any additional circuit.
In this link adding capacitor is suggested on Rn wires.

Yes, but it does not explain what these capacitors are there for. It could be that the "body" is kept at some DC potential far different from Vdd/2, could be a requirement to DC-isolate the "body" from the circuit altogether (that could be the reason to also have the two more capacitors in the feedback loop of the OPAMP at the bottom of the diagram) or it could be that some non-polarizable electrodes were used (such as AgAgCl). If you want to follow this link - install all 4 capacitors and connect both INAMP inputs to the output of U3 with two larger resistors, 1MΩ or so. Thing to watch out with these 4 capacitors would be the wait time after Start Frequency command and before starting the measurements - this time should be long enough for the transients caused by these capacitors and resistors to settle and sine wave baseline to become stable.
I did solve the problem in simulation. I will test it on the PCB and I will post my results.
I noticed another strange behavior (maybe strange for me), the real and imaginary part have huge difference. See the picture below,
This is in the saline water, 2 wires are short together (T1 with R1 and T2 with R2).
What could be the reason.
Does your code convert these hex values to decimal? Imaginary value is negative, so it is max about 5 times larger than Real part. Not sure you need to worry about this difference as long as you can calibrate your system with a resistor and get reasonable results with an "unknown" resistor. When you connect resistor instead of saline, how different are the Re and Im values? Perhaps about the same?
I checked, real and imaginary value depends on the frequency in Hz, low input frequency give higher real value while higher input frequency gives higher imaginary values.
This is true for both resistor and saline (according to my test conditions).
Thanks
value depends on the frequency in Hz, low input frequency give higher real value while higher input frequency gives higher imaginary values.
How low and how high and at what clock frequency (MCLK)? The built-in "DFT" unit gives only approximation of the true DFT (in mathematical sense) and it is accurate enough only at higher frequencies and at a handful of frequencies when the chunk of sampled sine wave contains integer number of whole sinewave cycles fitting within the 1024-long sampling sequence.
Since a resistor does not have imaginary component in its impedance, one would expect all response to be found in Real register and Imaginary to be near zero. The reasons why the resistor response appears as a negative value in the Imaginary register are not explained in the documentation, but the good news is that it does not really matter as the calibration procedure eliminates this discrepancy by producing complex system gain (or system gain and system phase) which allows to arrive at the correct values when measuring the unknown impedance.

Sorry I was busy in something. Check the doc please. This is n saline water, start frequency 20k and 5k increments in each 15 steps.

The data looks OK, except the values from the Re and Im registers have to be converted to decimals taking into account that the highest bit is the sign, so any reading above 32767 (hex 7FFF) is a negative value, so should be converted as reading = reading - 65536 (hex 10000).
