Current ratio controller CRC2 for electrodeposition

Review of Scientific Instruments, 1995
For the quasicontinuous potentiostatic electrodeposition of compound semiconductors, up to four injection anodes of different and differently changing resistances were used simultaneously. The design of an automatic current control unit to keep the relative anodic currents constant is shown.

The Precise Measurement of Current Ratios

IEEE Transactions on Instrumentation and Measurement, 1964
The development of the current comparator, a three-winding current ratio transformer, is reviewed and its characteristics as an alternating current ratio standard are analyzed. Particular attention is given to the use of magnetic shielding and its effect on the accuracy and usefulness of the device.

SIM Comparison of AC Current Ratio Using Instrument Current Transformers

2020 Conference on Precision Electromagnetic Measurements (CPEM), 2020
An AC-current-ratio comparison was performed in order to compare the measurement capabilities of NMI's in the Inter-American Metrology System (SIM), in the field of calibration of instrument current transformers, and link it with the European round of EURAMET through PTB. This paper shows preliminary results.

Circulating Current Ratio for DC SQUIDs

Journal of Superconductivity and Novel Magnetism, 2010
The circulating current in one Josephson junction of a DC SQUID is in the direction of translation current while in the other Josephson junction is in the opposite direction. Therefore, one interesting function is the circulating current ratio (CCR) which we define as: CCR = (dissipative translation current1 − circulating current)/(dissipative ...

Direct Display of Varying Current Ratio

IEEE Transactions on Instrumentation and Measurement, 1964
The ratio of two currents in function of any third quantity may be measured directly with the aid of pulse techniques. Sample pulses are taken from both currents by the same gating process while the duty cycle is changed in order to keep the time average of the pulsed denominator current constant.

Compensation in variable ratio current mirrors

IEEE Journal of Solid-State Circuits, 1997
The accurate control of the current ratio of a variable ratio bipolar current mirror is affected by the finite transistor current gain. Compensation for errors due to low current gain and mismatching of emitter efficiencies can be introduced to cancel these errors.

Electrical field affected by current decrement ratio at base current

2014 IEEE 41st International Conference on Plasma Sciences (ICOPS) held with 2014 IEEE International Conference on High-Power Particle Beams (BEAMS), 2014
Recently, the stable supply of electric power is indispensable in a power generation, and a transmission and distribution system of electric power. Therefore, many researchers have researched abnormal phenomenon of power system which is obstacle to the power transmission and distribution.

Financing Current Operations and Efficiency Ratio Analysis

2020
Current financing encompasses managing and utilizing current assets, and incurring and repaying current debt. The current assets of a firm differ from fixed assets; these differences are not abrupt but represent a continuum. The current assets (cash, receivables, inventory, etc.) support the short-run operations of the business. Current assets are what

A simple monolithic current-gain cell for large current ratios

International Journal of Electronics, 1980
A simple current-gain circuit is presented which generates large temperature insensitive current ratios accurately defined by small ratios of resistance and device area. Precision better than 1% and 100 ppm/°C is obtained in practice. A gain-bandwidth product of 1 GHz has been measured.
