The device's fully differential input structure features high common-mode rejection
ratio (CMRR) of more than 100 dB and a high impedance of more than 500 MOhms, which results in improved low common-to-differential mode conversion.
8, the measured common-mode rejection
ratios of all types of the corresponding transfer functions are shown.
Specifications include 5-MHz sampling speed, an 18-bit A/D converter, and 80-dB at 100-kHz common-mode rejection
The amplifier enables higher common-mode rejection
ratio (CMRR) and power supply rejection ratio (PSRR) at all gain settings.
Though this topology can achieve common-mode rejection
(CMRR) above 80 dB at DC, the CMRR dramatically degrades as frequency increases.
These filter showed stopband extension , good common-mode rejection
ratio (CMRR) , and dual-band  performances.
Since this common-mode level can lead to undesired radiation and EMI problems that degrades the performance of high-speed circuitry, a lot of effort has been devoted to the design of differential devices with high common-mode rejection
To provide a simple figure-of-merit for characterizing the implement differential filter, the common-mode rejection
ratio (CMRR) can be defined by
A ground-sensing CMOS input that provides a common-mode rejection
ratio (CMRR) of 120 dB.
A high common-mode rejection
ratio improves the distortion performance of an amplifier when used in a non-inverting feedback configuration, which is the standard topology for most power amps.
The part of the equation being multiplied by VN is the common-mode rejection
ratio or CMRR.
These differential LNAs offer an optimum common-mode rejection
ratio (CMRR), K = CMRR = 20 log([A.
