Cochlear Distortion: Effect of Direct-Current Polarization
Science, 1969Intermodulation components (combination tones) appearing in microphonic potentials were measured from guinea pig cochleas with and without polarizing direct currents passing through the cochlear partition. At moderate intensities of stimulus the polarization had a qualitatively different effect on the distortion components than on their eliciting ...

The Measurement of Distortion Current and Distortion Power
IEEE Transactions on Instrumentation and Measurement, 1984A converter for resolving current or voltage into three mutually orthogonal components-active, reactive, and distortion-is suggested. The described system confirms the possibility of measuring the distortion current and distortion power on the basis of the time-domain approach.

Influence of harmonic distortion in current transformer
2016 17th International Conference on Harmonics and Quality of Power (ICHQP), 2016This study aims to evaluate the performance (accuracy assessment) of current transformers in the presence of harmonic distortion. Using the software ATP-Alternative Transients Program, an equivalent CT circuit model was validated and the simulation results were compared with tests performed in prototypes.

Distortion analysis of switched-current circuits
ISCAS '98. Proceedings of the 1998 IEEE International Symposium on Circuits and Systems (Cat. No.98CH36187), 2002A distortion analysis based on the large signal behavior of the basic switched-current memory cell is presented. In the first part, based on a closed form solution of the step response, distortion due to the settling error is addressed. In the second part, distortion caused by clock-feedthrough is analysed. The solutions are compared with simulated and/

Harmonic distortion in switched-current circuits
Proceedings of 1997 IEEE International Symposium on Circuits and Systems. Circuits and Systems in the Information Age ISCAS '97, 2002Harmonic distortion in basic Switched-Current (SI) cells is investigated and closed-form equations are presented here, for the first time, concerning the effects of V/sub t/ mismatch, clock-feedthrough, and signal dependent output conductance. We show that with short channel transistors the variation of the output conductance is the dominant source of ...

A compensation algorithm for the distorted secondary current of a current transformer
Eighth IEE International Conference on Developments in Power System Protection, 2004Current transformer (CT) saturation may cause the mal-operation or operating time delay of protection relays. In this paper, a new algorithm for the compensation of the distorted secondary current due to CT saturation is suggested. The secondary current can be expressed as the linear combination of sinusoidal and exponential signals, if no saturation ...

Nonlinear distortion in current-feedback amplifiers
Microelectronics Journal, 1985A systematic method to characterize the nonlinear distortion in current-feedback amplifiers is described in this paper. This technique is easy to apply and allows us to determine analytical expressions for 2nd and 5th coefficients of harmonic distortion for single stage amplifiers. It is also applicable to differential pairs.

Comprehensive distortion compensation of grid-connected inverter currents
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014The paper presents a comprehensive approach to the compensation of phase current distortion of grid-connected power inverters. Four different sources of current distortion are addressed: imperfect grid synchronization caused by the distortion in the grid voltages, voltage fluctuations in the dc link, time delays in the estimation of grid voltages, and ...

Predicting harmonic distortion in switched-current memory circuits
1993 IEEE International Symposium on Circuits and Systems, 1994The switched-current (SI) technique has recently been proposed as a cheaper alternative to the switched-capacitor (SC) technique. This stems largely from the fact that the analog signal processing functions performed by a SC circuit using linear capacitors and MOS transistors can be replaced by a SI circuit consisting solely of MOS transistors. At this
