Phase-Controlled Currents in Semiconductors
Physical Review Letters, 1995The direction of emission of photoexcited electrons in semiconductors is controlled by adjusting the relative phase difference between a midinfrared radiation and its second harmonic. This is achieved by using quantum interference of electrons produced with one- and two-photon bound-to-free intersubband transitions in AlGaAs/GaAs quantum well ...

Current controlled fully balanced current conveyor
APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008This paper presents a current controlled fully balanced second-generation current conveyor circuit (CFBCCII). The proposed circuit with the fully balanced structure can restrain odd order harmonic distortion and common-mode disturbing signal effectively. Furthermore, the circuit has the property of current controllability, which can adjust its interior

New current-mode current-controlled filters using the current-controlled conveyor
International Journal of Electronics, 1998New current-mode current-controlled filters are proposed. The proposed realization requires three dual-output positive/negative-type current-controlled current conveyors (CCCII±) and can simultaneously realize low-pass, high-pass and band-pass responses. Realization of notch and all-pass responses is feasible. The parameters ω0, ω0/Q0 and the band-pass

The current controlled current-mode amplifier proposed by Fabre et al. (1996, IEEE Transactions on Circuits and Systems—I, 43, 82) is reanalysed to show that it can work not only under small signal conditions, as suggested by Fabre et al., but also under large signal conditions. Simulation results which confirm the theory presented are included.

▪ Abstract M-current is a non-inactivating potassium current found in many neuronal cell types. In each cell type, it is dominant in controlling membrane excitability by being the only sustained current in the range of action potential initiation.

Average Current Control with Asymmetrical Sawtooth or Peak Current Control
2019 European Space Power Conference (ESPC), 2019Conductance 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 ...

So far, we have discussed duty ratio control of PWM converters, in which the converter output is controlled by direct choice of the duty ratio d(t). We have therefore developed expressions and small-signal transfer functions that relate the converter waveforms and output voltage to the duty ratio.

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.

CMOS Current-controlled Oscillators
2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007The work presented in this paper is about the design of current-controlled oscillators (ICO). Two ICOs are proposed. Aiming at reducing the duration of the short-circuit currents caused by slowly-changing voltages in the circuits, signal conversion blocks are introduced to generate sharp pulses.
