Common-mode rejection of the differential operational amplifier with shunt common-mode feedback

IEEE Journal of Solid-State Circuits, 1975
A simple expression is derived for the common-mode rejection ratio (CMRR) of the differential operational amplifier with shunt common-mode (CM) feedback. The CMRR is exclusively expressed in terms of a fractional unbalance of the bridge circuit composed of an input resistor pair and a shunt CM feedback resistor pair.

Common-mode rejection ratio redefined

IEEE Transactions on Instrumentation and Measurement, 1997
Redefining the common-mode rejection ratio (CMRR), a set of equations is derived for the common-mode gain and the CMRR of differential amplifiers. The results, which are consistent with practice and simulation, show that an amplifier's CMR may exceed the CMR of the active device(s) by intentional unbalancing of the circuit.

An ECG/EEG Common Mode Rejection Ratio Analyzer

Journal of Clinical Engineering, 1982
An ECG/EEG common-mode rejection ratio analyzer is discussed and its method of operation is analyzed. In addition to easily performed common-mode rejection ratio tests, this instrument also can perform linearity, frequency response and sweep-speed tests.

On the measurement of common-mode rejection ratio

IEEE Transactions on Circuits and Systems II: Express Briefs, 2005
In this brief, several commonly used measurement configurations for common-mode rejection ratio (CMRR) are analyzed and compared with the definition; their advantages and limitations are also discussed. Finally, an improved measurement setup is proposed to characterize CMRR more accurately according to its definition over wider frequency range.

Common-mode rejection limitations of differential amplifiers

IEEE Journal of Solid-State Circuits, 1976
The common-mode rejection ratio (CMRR) equations of the differential pair and differential cascade amplifiers are reformulated in terms of imbalances in the saturation current. Early voltage, and current gain parameters of the transport model of the bipolar transistor. The effect of source resistance on CMRR is included in the formulation.

Mitigation of scintillation noise by common mode rejection

SPIE Proceedings, 2005
There is increasing interest in free space optical communications as an alternative to fibre optics and radio frequency communications, particularly in 'last mile' applications and applications with weight and power restrictions e.g. communications with unmanned aerial vehicles.

Differential image sensor with high common mode rejection

Proceedings of the 31st European Solid-State Circuits Conference, 2005. ESSCIRC 2005., 2005
Image processing applications like tracking of moving objects typically involve the subtraction of two successive images. Doing this without the need for a large digital memory requires a sensor chip that does the subtraction in the analog domain. This paper provides insight in the critical issues of the design of such a differential image sensor.

Common-mode rejection of monolithic operational amplifiers

IEEE Journal of Solid-State Circuits, 1970
A simple expression is derived for the common-mode rejection ratio (CMRR) of monolithic operational amplifiers in terms of transistor processing parameters. The tradeoffs between transistor current gain and CMRR are investigated. The feasibility of 120-dB CMRR is demonstrated with a common-emitter differential pair. The addition of eight active devices

The Common-Mode Rejection of Transistor Differential Amplifiers

IEEE Transactions on Circuit Theory, 1966
The primary aim of differential amplifiers is amplification of differential-mode input voltages and the suppression of common-mode input voltages. The problem of common-mode rejection of transistor-differential amplifiers is investigated. It is shown that in addition to the known possibilities of biasing differential stage from a constant current ...
