A current-mode CCCII-based analog multiplier/divider

In this paper, an application of CCCII for a building block of a current-mode analog multiplier/divider is proposed. The proposed schematic is realized by employing only CCCIIs as active circuit elements and no requiring any external passive circuit elements. With a proper selection of the applied input currents, the proposed schematic can perform the functions as a four-quadrant current multiplication, a four-quadrant current division and an inverting or a non-inverting type of current amplification, without changing its topology. PSPICE simulation is used as the tool to confirm the performance of the proposed circuit.
