Abstract

This paper presents an imaging IC with readout front-ends (RFEs) based on a 1^st-order Δ-ΔΣ modulator (Δ-ΔΣ M) for electrical-impedance-tomography (EIT) systems. This allows the utilization of the readout data from all the electrodes, including even the current - inj ecting electrodes, without saturation, thus achieving much higher imaging contrast. The proposed EIT system achieves an input range of 468 mV_pp, corresponding to 1.56
