Some new circuit configurations for dual-input integrators and differentiators are proposed. The use of a multiplier device around the Operational Amplifier (OA) yields electronic tunability of their time-constant (To) by a Control Voltage (Vx). Experimental results in support of theoretical design and analysis are included.

A new current-mode dual-input configuration for the generation of a ratio (Y2/Y1) type network function using the second generation current conveyor (CC ) elements has been proposed. With nonideal CC s, a precise compensation of output current can be obtained simply by insertion of a grounded admittance (Yc). The design of precise insensitive current-mode integrator/differentiator type functional circuits follows directly if the Y1,2 admittances are suitably chosen as RC components.
