Abstract (2. Language):
The third generation current conveyor (CCIII) presented by Fabre is shown to be a useful active
element to pick up the current of a floating passive element. CCIII can be considered as a current
controlled current source with unity gain. The use of controlled sources with unity gain in the
design of active-RC filters leads to structures with tight design equations. In order to relieve these,
it may be useful to insert a gain larger than unity. The modified third generation current conveyor
(MCCIII) is a newly introduced active building block to realize this property and to provide new
possibilities in the circuit synthesis. In this paper, four new first-order allpass filter configurations
employing a single modified third-generation current conveyor (MCCIII) are presented. To
demonstrate the advantages of the proposed circuit topologies, a quadrature oscillator is designed
employing the proposed allpass sections. SPICE simulation results verifying theoretical analyses
are also included.
