CMRR

The ability of an amplifier to amplify a signal in the presence of electrical noise. The higher the number, the better the amplification.

Furthermore, it features with high CMRR, it is characterized by lower THD, and its structure is generally less complex in comparison with a fully-differential solution designed by the mirroring technique.
Some $450 million has been appropriated to CMRR since 2002.

The value of the CMRR may be used to quantitatively discuss the degree of resemblance between the implemented differential filter.
CMRR represents the splitter rejection of an undesired common-mode output signal resulting from a single-ended input signal.
The sEMG signals were amplified by using a multi-channel, isolated biomedical signal amplifier BM623 (Biomedica Magoni) with an input impedance >10 MOhm and CMRR >100 dB.
The TS200 Modulated Power Supply is a unique instrument for many test and measurement applications such as LDO PSRR measurement, battery simulator, op amp CMRR measurement, function generator amplifier, transient response test, four-quadrant power supply, lab power amplifier and more.
These devices also offer high CMRR and PSRR for improved noise performance.
Otra opcion fue utilizar un amplificador de instrumentacion AD620 de la National Instruments, que permite una ganancia maxima en un factor de 1000, tiene un CMRR de 100 dB, una impedancia de entrada de 10GQ y, por lo general, se usa en instrumentos de medicina como ECG, sistemas de adquisicion de datos, control de procesos industriales, entre otros.
These differential LNAs offer an optimum common-mode rejection ratio (CMRR), K = CMRR = 20 log([A.
