Moreover, the
common-mode rejection ratio (CMRR), noise performance and offset can be improved even further by deploying the proposed IA in conjunction with the chopper stabilization technique.
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.
Exceptional
common-mode rejection ratio (CMRR) across a broad frequency range
The true-differential function blocks generally feature very high
common-mode rejection ratio, but the complexity of the circuit topology significantly increases [4]-[8].
It also offers a temperature coefficient of [+ or -]0.05 [micro]V/[degrees]C and a
common-mode rejection ratio of [greater-than]150 dB, The proprietary ISO-Channel[TM] technology provides 1,000-V galvanic isolation channel-to-channel and [+ or -]500 V to earth ground.
The 33411A offers a 140 dB
common-mode rejection ratio up to a maximum of 500 V, which sufficed for the 61/2-digit accuracy the customer needed.
The Ampzilla 2000 uses two stages of differential voltage amplification, instead of a single stage, to enhance the
common-mode rejection ratio. In turn, a common-mode voltage must be set at both the first- and second-differential amplifier outputs (add another feedback loop).
A high
common-mode rejection ratio (CMRR) is essential for strain gage amplifiers.
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.
