High CMRR instrumentation amplifier for biomedical applications

2007 9th International Symposium on Signal Processing and Its Applications, 2007
A new low-voltage single-power high CMRR and PSRR instrumentation amplifier is developed for biomedical applications. The proposed circuit uses a new structure to solve the conventional circuitspsila problems. Under similar conditions for comparison, the simulation results show the proposed circuits have better performances than conventional circuits ...

CMRR enhancement techniques for current-mode instrumentation amplifiers

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2000
The current-mode instrumentation amplifier based on second-generation current conveyors (CCII) offers many advantages over conventional instrumentation amplifier architectures. It does not need any matched components to reach high CMRR and its bandwidth is not gain-bandwidth product limited.

High CMRR, second generation current-mode instrumentation amplifiers

1993 IEEE International Symposium on Circuits and Systems, 2002
Common-mode bootstrapping techniques are used to produce high CMRR second generation current-mode instrumentation amplifiers. Simulation results, which take component mismatch into account, show CMRR performance better than 70 dB at 100 kHz for unity differential gain. >

High CMRR power efficient neural recording amplifier architecture

2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011
This work presents an architecture of neural recording amplifier based on a modified differential difference amplifier (DDA). The proposed circuit improves the performance with respect to capacitive feedback neural amplifiers and standard DDA based amplifiers by taking advantage of the high CMRR achievable in a DDA without jeopardizing the power ...

CMRR frequency response of CMOS operational transconductance amplifiers

IEEE Transactions on Instrumentation and Measurement, 2000
In this paper an accurate and complete analysis of the CMRR for the most commonly used CMOS OTA's has been carried out. The analysis provides equations which can profitably be used in the design of high-accuracy integrated amplifiers to be employed in instrumentation circuits. The analysis shows that the CMRR of these circuits is highly affected by two

Capacitively coupled ECG measurements - a CMRR circuit improvement

2017
A typical galvanic-connected electrocardiogram (ECG) measurement system utilizes two signal’s electrodes and a third one in driven-right-leg (DRL) circuit for improving a common-mode rejection ratio(CMRR) of the acquisition system. In capacitive-coupled ECG similar techniques are used, however it is expected, that the utilized DRL subsystem is formed ...

[The nursing consultation in a CMRR].

Revue de l'infirmiere, 2017
Resource and research memory centres (CMRRs) cater for patients with a cognitive disorder, usually with memory loss. Their aim is to establish if there is an underlying neurodegenerative pathology, Alzheimer's disease or related syndrome.

CMOS Differential Stage with Improved DC Gain, CMRR and PSRR Performance

2019 26th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2019
New circuit solutions able to operate under sub-1V supplies must be developed by analog designer to counteract the low intrinsic gain and limited rejection to common-mode and power supply disturbances offered by nanometer CMOS technologies. In this communication, an approach originally developed as a common-mode control loop for body-driven amplifiers,

Analysis of CMRR in Doubly-Tuned Transformer Baluns

IEEE Transactions on Circuits and Systems II: Express Briefs
This work rigorously investigates circuit techniques that aim at increasing the common-mode rejection ratio (CMRR) in a transformer-based doubly-tuned balun network. The presented analytical results are able to predict and quantify the CMRR for various circuit solutions employed in the literature. Moreover, they are able to predict the conditions under

[Anatomy of the CMRR and proposition of functioning].

Therapie, 2013
The main objective was to have a view of the functioning of the Centers Memory of Resources and Research (CMRR) to identify the difficulties which can interfere in the industrial clinical trials. The secondary objective was to make a proposal to optimize them.Questionnaires were given in all CMRRs.One hundred thrity-five questionnaires were retrived ...
