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.

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.

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.

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

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.

Differential amplifiers that reject common-mode currents

IEEE Journal of Solid-State Circuits, 1971
The transistor differential pair is analyzed and it is shown that the common mode rejection ratio (CMRR) is limited both in magnitude and bandwidth by device parameters. The performance is not significantly improved by series common-mode feedback. It is shown that amplifiers with shunt common-mode feedback reject common-mode input currents and that ...

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 ...

Research on Common-Mode Rejection Quartz Crystal Resonators

2007 International Conference on Information Acquisition, 2007
The force sensitive characteristic of multi-resonator assembled on one crystal are studied based on analyze of the force sensitive characteristic of AT-cut quartz crystal resonators and the interior vibration wave transmission in crystal. According to the common-mode rejection theory, the resonance frequency of resonators on different places is ...

Finite Common-Mode Rejection in Fully Differential Nonlinear Circuits

IEEE Transactions on Circuits and Systems II: Express Briefs, 2011
In this brief, it is highlighted that fully differential nonlinear circuits, even though perfectly symmetrical, can be significantly sensitive to common-mode (CM)/power-supply (PS) interference and can be affected by even-order distortion. The cross-modulation mechanism between CM and differential input components, which gives rise to such unwanted ...
