Detection of 10 dB vacuum noise squeezing at 1064 nm by balanced homodyne detectors with a common mode rejection ratio more than 80 dB

Conference on Lasers and Electro-Optics, 2019
We report our implementation of a squeezer, by generating squeezed vacuum state at 1064 nm through a bow-tie optical parametric oscillator cavity operated below the threshold. With the help of our home-made balanced homodyne detector (BHD), characterized

Simulation and Measurement of Differential Probe Gain Flatness and Common Mode Rejection Ratio

UK, Europe, China Millimeter Waves and THz Technology Workshop
The gain flatness of a differential probe with $\mathbf{1 0 0}$ times attenuation gear is simulated and measured. A method for simulating the common-mode rejection ratio (CMRR) using Monte Carlo in Advanced Design System (ADS) is presented.

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 ...
