Current Feedback Amplifiers (CFA) are discussed in this report. Current Feedback Amplifiers employ the current mode of signal processing to achieve higher gain-bandwidth product and greater slew rates than those of a Voltage Feedback Amplifier (VFA). The Current Feedback Amplifier topology has an inherent advantage over that of the the Voltage Feedback Amplifier, wherein the amplifier gain can ...

Abstract— This paper proposes a procedure for converting a class of Op Amp-, FTFN-, CCand CFAbased voltage mode circuits to corresponding current mode circuits without requiring any additional circuit elements and finally from Op Amp-based voltage mode circuits to any of the FTFN, CC and CFA current mode circuits. The latter circuits perform better at high frequency than the former ones. The va...

In this paper, a current-mode all-pass filter employing single multi-output dual-X second-generation current conveyor, a grounded resistor and a grounded capacitor is proposed. The circuit is as good as ideal for current-mode cascading by possessing low input and high output impedances. The use of grounded passive components makes the circuit, ideal for IC implementation. The effect of non-idea...

Large, outdoor Belt Conveyor Systems for bulk materials are major sources of industrial noise and frequently become an environmental emissions issue for many existing and proposed plants. Deficiencies in the industry’s understanding of the complex, underlying conveyor noise generating mechanisms has meant there are relatively few practical and cost-effective noise management strategies. On the ...

In this research, we studied the fault recognition algorithm of steel cord conveyor belt, and obtained the wire ropes image by adopting the detection system of steel cord conveyor belt, so that the fault recognition algorithm of steel cord conveyor belt was proposed based on Fruit fly optimization algorithm. As we know that the fruit fly optimization algorithm is used for fault detection of the...

This paper describes two related topics. First, it is shown how the concept of the MOSFET-C integrator can be extended to single-amplifier filter biquads. Then a new differential-input balanced-output current conveyor (CCII) is presented, which has two essentially symmetrical and balanced signal paths. Using this CCII, a 4th-order lowpass filter cascade suitable for on-chip tuning is presented,...
