Current-Controlled Sinusoidal Oscillators Using Current-Controllable Building Blocks

2016
In many applications, one requires an oscillator or waveform generator whose frequency can be varied through either a single external voltage or an external current. In this chapter, a variety of such electronically controllable oscillators would be introduced using modern current-controllable building blocks. Electronically controllable quadrature and

Low-voltage current controlled current conveyor

Analog Integrated Circuits and Signal Processing, 2009
A novel second-generation Current Controlled Current Conveyor (CCCII) topology is introduced in this paper. Compared with the corresponding already introduced topologies, the proposed CCCII offers the advantage of low-voltage operation capability. In addition, due to the absence of PNP or PMOS transistors for handling ac signals, its performance in ...

Differential CMOS current controlled current scalor

2015 International Symposium on Signals, Circuits and Systems (ISSCS), 2015
In this communication we present a differential current controlled current scalor designed in a 0.18u CMOS technology and study the influence of its nonideal behavior on the scaling properties. The scalor exhibits very good stability with temperature, high linearity, bandwidths and dynamic range. Several examples for the scaling property are presented.

Robust Fault-Tolerant Predictive Current Control for Permanent Magnet Synchronous Motors Considering Demagnetization Fault

IEEE transactions on industrial electronics (1982. Print), 2018
In this study, a robust fault-tolerant predictive current control (RFT-PCC) algorithm based on a composite observer is proposed for permanent magnet synchronous motors (PMSMs), which can eliminate the influence of motor parameter perturbation and ...

A new differential current- controlled current conveyor and its differential ladder current-controlled current-mode filter

2007 International Workshop on Electron Devices and Semiconductor Technology (EDST), 2007
the paper presents a new differential current - controlled second generation current conveyor circuit with multiple outputs (MO-DCCCII). The principle of the circuit is analyzed in detail. In this circuit, the voltage relations between the differential input Y and the differential terminal X can be tuned by the extra bias current and no restriction is ...

Predictive Current Control for an Active Power Filter With LCL-Filter

IEEE transactions on industrial electronics (1982. Print), 2018
Voltage source inverter based active power filters are widely used for the compensation of harmonic currents, especially in industrial environments. Loads such as three-phase diode rectifiers, thyristor-based rectifiers or variable-speed drives can cause

Current controlled resistance

2017 9th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2017
This paper presents an application of operational transconductance amplifiers (OTA), namely a simulated resistance made with OTA. Its value can be controlled by the current polarization of the operational transconductance amplifier. It is also presented an immediate application of the simulated resistance, namely the low-pass filter.

Average Current Control with Asymmetrical Sawtooth or Peak Current Control

2019 European Space Power Conference (ESPC), 2019
Conductance control within SMPS (Switch Mode Power Supply) is typically implemented relying either on the ACC (Average Current Control) or on the PCC (Peak Current Control) technique. An in-depth analysis of the PCC dynamics has been published in the past, highlighting that such technique responds to a feedback control loop scheme covered by Laplace ...

Bidirectional current-controlled PTAT current source

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1994
In this paper a new current-source proportional to absolute temperature (PTAT) is introduced. It is adjustable and does not require any starting current. The circuit is obtained from a mixed translinear loop of only four transistors. A first generation current conveyor is added in order to obtain a floating output current.
