LCR-Meter- Auto balancing bridge


In the previous post signal generator is implemented using 555 timer. The next extension for this is to find impedance of the DUT using self balancing bridge method. It includes Opamp, which is used for converting current to voltage through the DUT. By comparing the output and input reference voltage from signal generator the impedance of the DUT can be estimated.





Note: The design files are in kiCAD and can be found in my github profile:
