TL;DR: In this article, a synthesis procedure is presented whereby the network function T (s) can be realized as an active RC multiport network with grounded ports, based on V(s) = T (S) U (s), where T is a q × p matrix of real rational functions of the complex variable s, the realization requires a minimum number of grounded capacitors and no more than 2 (p+n) inverting, grounded voltage amplifiers or p+n differential output.
Abstract: A synthesis procedure–easily implemented as a digital computer program– is presented whereby the network function T (s) can be realized as an active RC multiport network with grounded ports. Based on V (s) = T (s) U (s), where T (s) is a q × p matrix of real rational functions of the complex variable s, the realization requires a minimum number of grounded capacitors–n = degree { T (s)}–and no more than 2 (p+n) inverting, grounded voltage amplifiers or p+n differential output, grounded voltage amplifiers. Note: These properties of the realization are desirable if the network is to be fabricated as an integrated circuit.

TL;DR: In this paper, a synthesis procedure, easily implemented as a digital computer program, is presented whereby any p \times p matrix Y(s) of real rational functions of the complex frequency variable s can be realized as the short-circuit admittance matrix of a p -port active RC network.
Abstract: A synthesis procedure, easily implemented as a digital computer program, is presented whereby any p \times p matrix Y(s) of real rational functions of the complex frequency variable s can be realized as the short-circuit admittance matrix of a p -port active RC network. The realization requires a minimum number of capacitors- n = degree \{Y(s)\} -and no more than 2(p+n) inverting common ground voltage-controlled voltage sources. All the capacitors and ports are grounded.

TL;DR: In this paper, a new and practical synthesis procedure is presented for the realization of an arbitrary n × n matrix of real rational functions of the complex frequency variable as the short-circuit admittance matrix of a transformerless active RC n-port network.
Abstract: A new and practical synthesis procedure is presented for the realization of an arbitrary n × n matrix of real rational functions of the complex frequency variable as the short-circuit admittance matrix of a transformerless active RC n-port network. The realization requires a theoretically minimum number of capacitors p, where p is the degree of the matrix, and no more than (n + p + 1) grounded finite-gain phase-inverting voltage-controlled voltage sources. All the capacitors and ports are grounded. The freedom implicit in the synthesis procedure allows the inclusion of constraints on the passive element values. Furthermore, in special cases the realization is achieved with a reduced number of conductances and voltage-controlled voltage sources. The synthesis procedure is simple to apply and can readily be implemented on a digital computer. Several examples are given.

TL;DR: In this article, it is proved that an arbitrary n × n matrix of real rational functions of the complex frequency variable can be realized as the short-circuit admittance matrix of a grounded transformerless active RC n-port network containing (n+1) grounded finite-gain phase-inverting voltage-controlled voltage sources (VCVSs).
Abstract: A new procedure for the synthesis of active RC networks when grounded finite-gain phase-inverting voltage-controlled voltage sources serve as active elements is developed. It is proved that an arbitrary n × n matrix of real rational functions of the complex frequency variable can be realized as the short-circuit admittance matrix of a grounded transformerless active RC n-port network containing (n+1) grounded finite-gain phase-inverting voltage-controlled voltage sources (VCVSs). In general all the (n+1) grounded VCVSs are necessary. The structure proposed to prove a general theorem is later simplified for the realization of a restricted but important class of real rational matrices to obtain considerable savings in the computation volume and in the number of passive components used for the realization of the network. Examples are given to illustrate presented synthesis procedures.

TL;DR: In this article, a new and practical technique for synthesizing arbitrary rational admittance matrices is presented, which includes the inclusion of the RC constraints and the ability to include the frequency-dependent nonideal controlled-source models in the synthesis procedure.
