The equivalence of third-order low-pass structures

Equal-valued capacitor active RC networks due to Gopal are shown to be equivalent (except for a buffer amplifier) to those of Dutta Roy and Malik.

4th-order EVC-ARC networks

New circuits are presented for the realization of fourth-order equal-valued capacitor active RC networks. Practical realizations indicate the existence of design restrictions on certain combinations of amplifier gain.

The synthesis of biquadratic passive RC impedances with equal-valued capacitors

The purpose of this paper is to present a method for synthesizing a class of second-order RC driving-point impedances with minimum total capacitance using equal-valued capacitors. This method has practical applications for the design of the passive portions of integrated circuits, in which cost minimization is a main objective. A network topology satisfying the requirements of equal and minimum total capacitance is developed, and specific element values in this topology are derived to match the desired impedance. Certain realizability conditions for this synthesis are derived.

An equal-valued capacitor active RC network realization of a fourth-order low-pass butterworth characteristic

This letter describes an active RC network which realizes a fourth-order low-pass Butterworth characteristic. It requires one active element and has the practical advantage that all capacitors have the same value. A design chart is included.

Design tables for low-pass equal-valued capacitor active RC networks

The design of low-pass equal-valued capacitor structures is discussed and applied to a number of approximating functions. Particular attention is paid to the suitability of the networks for realization in microelectronic form.

The realization of high-pass equal-valued capacitor filters †

Abstract The paper presents design tables for high-pass RC active filters having capacitors of equal value. The functions realized are of the third-order Butterworth and Chebyshev variety. Account is taken of the resistor spread, total resistor stun and of the summed network sensitivity.
