1.Please suggest the circuit diagram for 4-electrode configuration for human body thoracic impedance measurement range 0-60 ohm using ad5933
2.I want inject ac current 200uA at 100khz ...please suggest the Resistor and capacitor value in the circuit diagram
3.Two electrodes for injecting the current and another two electrodes for sensing the voltage
4.I want operate the circuit at single power supply
5.I have referred the link: AD5933 4 Wire Configuration for low impedence (< 50 ohm) but there is no clarity in the diagram.Please suggest the circuit diagram for 4-electrode configuration for human body thoracic impedance measurement range
thanks for your suggestion
1.can you suggest the exact part no
2.please verify the following schematic
3. RC value for biasing the INAMP
4.C blockdc value=?
5. i am using Rcal =20ohm (human body impedance range 1-60 ohm) is it right?
6. selection of INAMP and gain resistor value
7. opamp part no
8.I am using this circuit for the impedance cardiography
