Development of neutron depth profiling at CMRR
Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2015Abstract A neutron depth profiling (NDP) system has been developed at China Mianyang Research Reactor (CMRR) at Institute of Nuclear Physics and Chemistry (INPC), CAEP. The INPC-NDP system utilizes cold neutrons which are transported along the C1 neutron guide from the cold neutron source.

CMOS High-CMRR Current Output Stages
IEEE Transactions on Circuits and Systems II: Express Briefs, 2007Two CMOS current output stages are presented. Compared to the traditional solution, which exhibits unbalanced operation, the proposed ones exploit an auxiliary high-gain feedback loop which provides differential drive, thereby highly improving the common-mode rejection ratio (CMRR).

Current output stage with improved CMRR
10th IEEE International Conference on Electronics, Circuits and Systems, 2003. ICECS 2003. Proceedings of the 2003, 2004A technique to increase the common-mode rejection ratio of traditional current output stage is presented. The solution exploits an auxiliary high-gain feedback loop which also approximately doubles the differential transconductance. SPICE simulations using the model parameters of a 0.8-/spl mu/m CMOS process arc found in remarkable agreement with ...

Fully Differential Class-AB OTA with Improved CMRR
Journal of Circuits, Systems and Computers, 2017This paper presents a fully differential class-AB current mirror OTA that improves the common-mode behavior of a topology that presents very good differential-mode performance but poor common-mode rejection ratio (CMRR). The proposed solution requires a low-current auxiliary circuit driven by the input signal, to compensate the effect of the common ...

High CMRR current-feedback operational amplifier
International Journal of Electronics, 2003Despite excellent high frequency and high speed performance, current-feedback operational amplifiers (CFOAs) generally exhibit poor common-mode rejection properties, which limits their utility. In this paper the authors analyse the conventional (CFOA) in terms of common-mode rejection ratio (CMRR) performance, and, having identified the mechanism ...

A CMOS single-ended OTA with high CMRR
ESSCIRC 2004 - 29th European Solid-State Circuits Conference (IEEE Cat. No.03EX705), 2004A high CMRR single-ended current-mirror OTA employing a novel current CMFB is proposed. The OTA input/output common mode range, die area, power and slewing speed are not affected. The settling speed is reduced by 5%-20%. The current CMFB boosts the OTA CMRR by a factor of 30 while allowing integration of conventional OTA improvements.

High-CMRR Current Amplifier Architecture and Its CMOS Implementation
IEEE Transactions on Circuits and Systems II: Express Briefs, 2006A novel current operational amplifier, in which the traditionally adopted input current follower is replaced by an input stage that exhibits current gain and single-input-to-differential-output conversion, is presented. Due to this, increased values of both dc gain and common-mode rejection ratio (CMRR) are obtained in the overall amplifier.
