Transfer-Function Synthesis Using An Operational Amplifier

A new scheme is presented for the realization of a rational open-circuit voltage ratio transfer function by a grounded RC two-port network with an operational amplifier embedded in it. The procedure is applicable in general to transfer functions of any complexity and can realize minimum phase and non-minimum phase transfer functions, including those having zeros of transmission on the positive real axis. The merits of the new scheme as compared with the presently known methods are specified. Examples are included to illustrate the synthesis procedure. © 1967, Walter de Gruyter. All rights reserved.
