Sensors and Actuators A: Physical, 2000
The current-output fluxgate may be tuned by using a serial capacitor. Such tuning increases the sensor sensitivity in the situation when the pick-up coil has a low number of turns. We achieved a signal/feedthrough ratio improvement by a factor of 5. The measured parameters fit the simplified theoretical model within 20% deviation.

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 ...

A high output impedance current source
Physiological Measurement, 1994A high output impedance current source was required for electrical impedance tomography (EIT) applications capable of operating up to 200 kHz. The architecture is based on operational-amplifier power-supply current sensing and produces a predominantly capacitive output impedance, which for the design presented is approximately 1.2 pF.

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).

A new current-controlled multiple-output current-conveyor
Proceedings of 1997 IEEE International Symposium on Circuits and Systems. Circuits and Systems in the Information Age ISCAS '97, 2002A new second-generation multiple-output current-controlled current-conveyor (MOCCCC) is presented. It has current-transfer ratios that can be varied by control currents. It is characterized by approximately constant bandwidth over a wide range of current-transfer ratios.

Cylindrical Direct‐Current Triboelectric Nanogenerator with Constant Output Current
Advanced Energy Materials, 2020AbstractIn this article, a cylindrical direct‐current triboelectric nanogenerator (DC‐TENG) that can generate an almost constant current output with a low crest factor by phase coupling is reported for the first time. Here, the influence of phases (P) and groups (G) on the DC‐TENG is investigated.

Current-transformer output and application charts
Electrical Engineering, 1944The performance of a multiratio current transformer is most simply represented as a function among the admittance vector locus of the core for one turn, the secondary-turn number N, and the secondary impedance Z. If the ratio of N2/Z is used as a variable, extremely simple application charts for ratio correction factor in relation to primary currents ...

Summary This paper reports five new single-input multiple-output current-mode multifunction filter circuits which can simultaneously realise three basic filter functions all at high impedance outputs. The circuits employ only the same type of active elements, grounded passive components, andno element matching conditions are imposed.
