TL;DR: SCAPN as discussed by the authors is a computer analysis program developed at the University of Illinois for a broad class of switched-capacitor (SC) circuits, which is used for nonlinear distortion and sensitivity analysis for several example circuits.
Abstract: SCAPN is a computer analysis program developed at the University of Illinois for a broad class of switched-capacitor (SC) circuits. This paper illustrates SCAPN's nonlinear distortion and sensitivity analyses for several example circuits. In particular, a thorough sensitivity analysis is presented for five network realizations for a fifth-order elliptic anti-aliasing filter used in CODEC systems. It is shown how the large quantity of sensitivity data produced by SCAPN can be analyzed to reveal relative merits of alternative circuit realizations.

TL;DR: An exact design of switched-capacitor bandpass filters is presented and a new technique based on the distributed circuit theory with a suitable bandpass transformation is presented.
Abstract: An exact design of switched-capacitor bandpass filters is presented. This new technique is based on the distributed circuit theory with a suitable bandpass transformation. The theoretical aspects of this method are given as well as the simulated results using a switched-capacitor circuit-analysis program.

TL;DR: In this article, two low-sensitivity switched-capacitor filter structures implementing the strays-insensitive switched-Capacitor biquads are presented based on a generalized multiple-loopfeedback (GMF) topology.
Abstract: Two low-sensitivity switched-capacitor filter structures implementing the strays-insensitive switched-capacitor biquads are presented. They are based on a generalized multiple-loop-feedback (GMF) topology, which is formed by the combination of the follow-the-leader-feedback (FLF) and inverse follow-the-leader-feedback (IFLF) topologies. Design equations that relate the feedback and feedforward parameters to the discrete-time transfer function are derived for both structures. Sensitivity analyses of the proposed structures as well as of the previously published ones are carried out using Monte Carlo simulations. It was found that the modified GMF structure possesses a lower sensitivity with respect to capacitance ratios.

TL;DR: In this article, a synthesis for switched-capacitor filters, implementing stray-insensitive biquads and based on follow-the-leader feedback topology, is presented, where design equations that directly relate the capacitances to the transfer function coefficients are derived.
