Abstract
Techniques are disclosed for measuring bioimpedance of a biological object with an alternating current (AC) source, a pair of electrodes, a reference load, a switching arrangement switchable between a first switch condition and a second switch condition, and measuring electronics. When the switching arrangement is in the first switch condition, the AC source is applied across the reference load and a group delay of the measuring electronics is determined. When the switching arrangement is in the second switch condition, and the pair of electrodes is in contact with the biological object, a voltage waveform based on the AC source being applied across the pair of electrodes is measured and a calibrated voltage waveform is determined, the calibrated voltage waveform being corrected for the group delay. The bioimpedance value of the biological object is determined based on the calibrated voltage waveform.
