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

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 ...

Nonlinear Average Current Control Using Partial Current Measurement
APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007This paper presents a nonlinear average current control method which regulates the true average of the inductor current by using the switch current as the feedback signal. The method is simple and requires no compensator design. Unlike existing average current control where the control bandwidth is limited to about one tenth of the switching frequency,

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.

Annual Review of Physiology, 1997
▪ 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.

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

Current-Controlled Sinusoidal Oscillators Using Current-Controllable Building Blocks
2016In 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, 2009A 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), 2015In 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.
