A novel current-mode multiplier/divider employing only single Dual-Output Current Controlled CDTA

This paper reviews a circuit which is analog multiplier/divider using single Dual-Output Current Controlled Current Differencing Transconductance Amplifiers (DO-CCCDTA). The proposed circuit can function as four-quadrant multiplier and two-quadrant divider without changing a circuit topology. A constant value of multiplication and division can be controlled via an input bias current. Without any external passive element requirements and using only single DO-CCCDTA, the proposed circuit is suitable to fabricate in IC. The circuit performances are depicted trough PSPICE simulations, they show good agreement to theoretical analysis.
