  In this paper, we report an improved implementation of an inductorless third
order autonomous canonical Chua's circuit. The active elements as well as the
synthetic inductor employed in this circuit are designed using current feedback
operational amplifiers (CFOAs). The reason for employing CFOAs is that they
have better features such as high slew rate, high speed of operation, etc.,
which enable the circuit to operate at higher frequency ranges, when compared
to the circuits designed using voltage operational amplifiers. In addition to
this, the inclusion of CFOAs provide a buffered output which directly represent
a state variable of the system. The Multisim simulations in the time and
frequency domains confirm the theoretical estimates of the performance of the
proposed circuit at high frequencies. It is also confirmed through hardware
experiments.
