Nth-order voltage transfer function synthesis using a commercially available active component: signal-flow graph approach

The author presents a general synthesis method for the realisation of an nth-order voltage transfer function using an active RC circuit comprising a commercially available active component, AD844, which is equivalent to the combination of a second generation current conveyor having a gain of +1 (CCII+) and a unity gain voltage buffer. The use of this active component simplifies the implementation, making the proposed circuit attractive
