Low harmonic distortion class AB CMOS current output stage

Proceedings of Third International Conference on Electronics, Circuits, and Systems, 2002
A novel high performance class AB current output stage which is based on active-gain enhanced cascoded mirrors is presented. It overcomes the non-linearity caused by channel-length modulation and provides a very high output resistance. The linearity performance of the proposed circuit, which is only limited by the fundamental constraints due to ...

Correlations Between Domain Wall Currents and Distortions

2021
As discussed in Sect. 2.4, in Pb(Zr0.2Ti0.8)O3, one mechanism for the appearance of conduction at ferroelectric domain wall involves the accumulation of charged defects such as oxygen vacancies at the domain boundaries, providing a conducting pathway. In materials where the domain wall conduction is provided by such defects, the currents at the walls ...

Voltage and current distortion generated by the CNC

2017 Progress in Applied Electrical Engineering (PAEE), 2017
The paper presents the results of voltage and current measurements performed in electrical drive system of CNC machines. The tests were made for different operation states of devices. We analysed the influence of nonlinear devices for current and voltage waveforms.

Estimating automobile chassis voltage distortion using load currents

IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat. No.03CH37468), 2004
This paper provides a model of the automobile chassis impedance for the purposes of predicting voltage distortion. A discrete-time model of the chassis and a method for identifying its parameters is introduced. The usefulness of the techniques developed in this paper are demonstrated using experimental data.

A Low Distortion, Current Feedback, Programmable Gain Amplifier

2005 IEEE International Symposium on Circuits and Systems, 2005
A programmable gain amplifier (PGA) is designed in a 0.18 /spl mu/m CMOS process, which makes use of current feedback building blocks. The voltage gain of the PGA can be changed from 0 dB to +60 dB with 2 dB steps and has a -3 dB bandwidth of 20 MHz. The PGA exhibits better than -60 dB spurious free dynamic range (SFDR) over the entire gain range at a ...

Frequency tripler with very little input-current distortion

IEEE Transactions on Magnetics, 1969
A three-phase output frequency tripler is presented which operates with very little input-current distortion. In a conventional frequency tripler, filters for eliminating the higher harmonics in the input current must be placed in the primary lines. The frequency tripler described in this paper has a mechanism which suppresses the higher harmonics.

Predicting harmonic distortion in switched-current memory circuits

1993 IEEE International Symposium on Circuits and Systems, 1994
The 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

Sources of Current and Voltage Distortion

Abstract The development in electronics and power electronics results that traditional loads, such as, for example, incandescent bulb-based lighting systems, meaning the linear ones, which do not cause harmonic distortion are superseded by current harmonics-generating loads.

Current transformer measurements of distorted current waveforms with secondary load impedance

1999 IEEE Africon. 5th Africon Conference in Africa (Cat. No.99CH36342), 2003
This paper evaluates current measurements with current transformers under distorted current conditions. Power quality assessment relies on the accurate measurement of current and voltage. Current transformers exhibit a good frequency response under distorted conditions, although this is only valid for a low impedance load on the secondary of the ...
