Abstract Experimental investigations were carried out in order to identify the portable device requirements for in-vitro muscle tissue monitoring over time. Based on these investigations, specifications measurement system defined considering type and amplitude of excitation signals (500 mV), frequency range (1 kHz–10 MHz) impedance (10 Ω–4 kΩ). For requirements, a structure is proposed based magnitude ratio phase difference detection using gain detector. To fulfill detector circuit's inputs, an interface circuit with error lower than 0.09% from 2 mV up 200 mV.
