Abstract:

This paper presents the design and implementation of a read-out chain for electrical impedance tomography (EIT) imaging. The EIT imaging approach can be incorporated to take spectral images of the tissue under study, offering an affordable, portable device for home health monitoring. A fast read-out channel covering a wide range of frequencies is a must for such applications. The proposed read-out channel comprising a programmable gain instrumentation amplifier, an analog-to-digital converter (ADC), and an ADC driver is designed and fabricated in a 0.18 μm CMOS technology. The proposed read-out chain operates over the wide frequency range of 100 Hz to 10 MHz, with an average signal-to-noise ratio of more than 60 dB. The entire read-out channel consumes between 6.9 and 21.8 mW, depending on its frequency of operation.
