In today’s world, medical professionals pay more and more attention to the development of diagnostic devices for patients. Developers are faced with the task of creating biomedical devices that have the conditions of non-invasiveness, as well as satisfying in terms of accessibility and technical and economic parameters. One of the non-invasive methods that requires special attention is bioimpedance. The bioimpedance analyzer finds wide application in various fields. However, it should be noted that there are problems of measurement accuracy, selectivity of measurements of the object under study, etc. There are a large number of analyzers, but all of them have basic scientific and technical problems associated with measurement error. In this paper, a block diagram is proposed, which has a distinctive feature from other bioimpedance measurement structures - it is the use of an independent current source and a differential amplifier, which will allow working with an object that has a high resistance between current and potential electrodes. The aim of the study is to model the measuring units of a bioimpedance analyzer. The main task of which is to develop a current source model capable of measuring at a high frequency up to 2 MHz.

In diagnostic medicine, in order to monitor physiological parameters that characterize the composition of the human body, the state of the respiratory system, in oncology and other areas, one of the informative parameters is bioimpedance. At the moment, when measuring bioimpedance parameters, much attention is paid to the methods and measurement accuracy. The biological object in contact with the electrodes under the influence of alternating current demonstrates a complex behavior of the impedance. In this article, from the metrological point of view, the contact electrode - biological object is analyzed; ways to reduce methodological errors due to the influence of electrodes are proposed, a model of a bioimpedance instrument is proposed.
