OverviewThe switched-capacitor resistorThe parasitic-sensitive integratorThe parasitic insensitive integratorThe multiplying digital to analog converterAnalysis of switched-capacitor circuitsA switched capacitor is an electronic circuit element implementing a filter. It works by moving charges into and out of capacitors when switches are opened and closed. Usually, non-overlapping signals are used to control the switches, so that not all switches are closed simultaneously. Filters implemented with these elements are termed "switched-capacitor filters", and depend only on the ratios between capacitances. This makes them much more suitable for use within integrated circuits, where accSee more on enpedia · Text under CC-BY-SA license

PDF fileswitched-capacitor filter breadboard. The circuit is built on a copper clad board which acts as a ground plane. The switched-capacitor filter and buffer operational amplifier are well bypassed. All leads are kept as short as possible and the switched-capacitor filter clock input is through a shielded cable. The second breadboard uses a single

PDF fileanalyze switched-capacitor ampliﬁers, considering unity-gain, noninverting, and multiply-by-two topologies. Finally, we examine a switched-capacitor integrator. 12.1 General Considerations In order to understand the motivation for sampled-data circuits, let us ﬁrst consider the simple continuous-time ampliﬁer shown in Fig. 12.1(a).

An adjustable switched capacitor circuit comprises a first stage 201, a second stage 202 and a switched capacitor circuit 204 coupling the output of the first stage 201 to the input of the second stage 202. The operating parameters of the second stage 202 are a function of the effective resistance of the switched capacitor coupling circuit 204.
