Comparing between three current source circuits for using in bio electrical impedance design

The current source circuit is one of the most important parts in the bioelectrical impedance devices and Bio Impedance tomography (BIT). There are many types of these circuits like (Howland, one op-amp, two op-amps, etc). In this study three types of electronic circuits are built and tested by using...
