Abstract
The front-end circuit for an impedance measurement comprises an excitation-terminal, intended to receive an excitation signal relative to a common ground, a first and a second input-terminal, intended to be connected to two electrodes, a first and a second output-terminal, whereby each one of the two output-terminals is intended to provide a measurement signal during a use of the front-end circuit in a measurement, preferably to an analogue to digital converter device; a first and a second mode selection-switch-unit, each with two mode switch-inputs, an operational amplifier and a reference resistor. During a measurement and depending on the state of the mode selection-switch-units, a feedback-loop of the operational amplifier comprises either a sample arranged between the two input-terminals or the reference resistor.
