Biquadratic voltage-mode filterThis paper presents a current feedback operational amplifier (CFOA) based on the topology of the second-generation positive current conveyor (CCII+) and an output buffer. The CCII+ is comprised of n-input and p-input balanced current mirror load OTAs with negative...

Two new linear, frequency-dependent macromodels for the Current-Feedback Operational Amplifier (CFOA) are introduced. Both macromodels simulate the actual performance of typical CFOAs for a wide range of frequencies. The first proposed macromodel suits manual calculations due to its relatively simple ...

Because they offer some significant advantages over conventional operational amplifiers, current feedback operational amplifiers (CFOAs) have been used instead of voltage operational amplifiers (VOAs) in new implementations of the chaotic Chua's circuit. In this study, after giving a comparative investiga...
The filters are built around the current-feedback operational-amplifier. In each case one or more of the parameters of the filter can be electronically controlled by adjusting the gain of an external amplifier built around the current-feedback operational-amplifier. Contrary to the current-mode ...
