8, the measured
common-mode rejection ratios of all types of the corresponding transfer functions are shown.
The Sherwood amplifier topology is unique in that it combines a complementary topology past the differential pair while still maintaining the high
common-mode rejection ratio of a differential pair with active current mirrors.
To evaluate the rejection of common-mode signals in preference to differential signals,
common-mode rejection ratio (CMRR) is used
The Ampzilla 2000 uses two stages of differential voltage amplification, instead of a single stage, to enhance the
common-mode rejection ratio.
An ADC's
common-mode rejection ratio (CMRR) specifies how well it will reject a common-mode signal in the presence of the differential signal you want the ADC to measure.
In this method, the
common-mode rejection ratio (CMRR) typically is limited to less than 20 dB (10:1).
at 5V), a high
common-mode rejection ratio (115 dB typ.
An important but often overlooked differential probe specification is derating of the
common-mode rejection ratio (CMRR) with frequency.
A high
common-mode rejection ratio (CMRR) of 86 dB (gain=5) effectively eliminates common-mode interference.
The CS3511 supports single-ended inputs or fully-differential inputs for improved
common-mode rejection ratio (CMRR) and operates from single 9 V or 12 V voltage supplies.
A high
common-mode rejection ratio provides a high immunity to transient noises, EMI and ground loops eliminations.
Additional performance features include optimal open loop gain (AOL), power supply rejection ratio (PSRR), and
common-mode rejection ratio (CMRR) -- all better than 100dB -- for improved dynamic range and gain accuracy.
