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 circuits like the Howland Current Source, Improved Howland Current Source, General Impedance Convertor, Wien Bridge circuit etc. This paper presents the comparative analysis of the available current sources and study of the best suited ones for the bioimpedance measurement and its various applications. Keywords—bio impedance, generalised impedance converter, howland current source, current source.
