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