| Abstract: | A 32-electrode data collection system for electrical impedance tomography (ETT) is presented. In this system, the demodulator is a multiplexed sample and hold (S&H) circuit followed by a voltage difference stage. This configuration provides high CMRR due to the low (almost DC) operating frequency of the signals the difference stage is required to process |
