TL;DR: In this paper, an integrated third-order low-pass filter is proposed, which can be built by means of capacitances, ordinary switches, and voltage inverter switches, the latter being quite simply realizable by electronic means.

TL;DR: In this paper, an approach to the design of nonlinear analog switched-capacitor (SC) circuits using building blocks is described, and a design example of an FSK demodulator with an SC phase-locked loop is demonstrated.

TL;DR: Using voltage inverter switches, exact analog sampled-data equivalents of Rs, Ls and Cs, as well as unit elements, can be designed with MOS capacitors and switches, which allows low power switched capacitor filters without operational amplifiers and with a frequency capability approaching the megahertz range.

TL;DR: In this paper, a real-time programmable switched capacitor (SC) second-order bandpass filter is presented, which is based on the voltage inverter switch (VIS) principle using inverse recharging devices.

TL;DR: In this paper, a programmable unit-element SC filter based on wave-flow networks was proposed for LPC synthesis, where the capacitive loading of every op amp is constant, thus simplifying the op amp design.
