Electrical impedance tomography. Improved wideband, high CMRR (common mode rejection ratio) instrumentation amplifier.

Clinical physics and physiological measurement : an official journal of the Hospital Physicists' Association, Deutsche Gesellschaft fur Medizinische Physik and the European Federation of Organisations for Medical Physics, 1992
A wideband high CMRR instrumentation amplifier is described. Based on a previously reported current-mode design, the improved amplifier features excellent CMRR performance of better than 60 dB up to 200 kHz with unity differential gain.

An ultra-high common-mode rejection ratio (CMRR) AC instrumentation amplifier for laplacian electrocardiographic measurement.

Biomedical instrumentation & technology, 1999
Laplacian electrocardiograms (LECGs) localize the moment of activation (MOA) of the heart noninvasively at a nearby point on the chest surface. Tripolar concentric ring (TCR) electrodes provide small, but well-defined, site-specific second spatial derivative signals of the potential on the chest surface for studying the activation sequence of the ...
