A Switched Capacitor Memristive Emulator
IEEE Transactions on Circuits and Systems II: Express Briefs, 2021 In this brief, we propose a mixed-signal circuit, emulating memristive behaviour. In specific, the design and implementation of a novel, low cost Switched Capacitor Memristor Emulator (SCME), is presented and studied. The proposed emulator utilizes the well-known switched capacitor technique for controlling its resistivity, thus creating its ...

The switching of capacitors differs from other switching by causing relatively large surge currents and possibly overvoltages. The performance of circuit breakers in this service has been found by recent experiments to depend on the power supply system as well as on the size of the capacitor banks.

Testable switched-capacitor filters
IEEE Journal of Solid-State Circuits, 1992A design-for-testability (DFT) methodology for switched-capacitor (SC) filters is presented, based on an architecture using some additional circuitry and providing extra capabilities for both off- and online test. A programmable biquad is used for on-chip comparison of the transfer functions for every filter stage.

Switched capacitor boost inverter
2016 IEEE 25th International Symposium on Industrial Electronics (ISIE), 2016The differential boost inverter (DBI) generates an alternating differential voltage from two dc-dc converters. The instantaneous output voltage can be higher or lower than the dc input voltage, however DBIs exhibit nonlinear control-to-output behavior in large-signal sense.

A LED Driver With Switched Capacitor
IEEE Transactions on Industry Applications, 2012The paper proposes a switched-capacitor converter fed at 24 V to drive power light emitting diodes (LEDs). In contrast to conventional constant dc current drivers, the current pulse is provided by this switched-capacitor. In the present driver, the capacitor is charged and discharged through the output and the current flow direction is controlled by ...

The filters we have studied in the two previous chapters are primarily based on the assumption that they are to be implemented in discrete or hybrid forms - thick-film or thin-film. Although the op amp may be fabricated in integrated-circuit (IC) form (sometimes in groups), it is actually treated as a separate entity for our purposes.

A programmable switched-capacitor filter
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002A switched-capacitor filter with independent programmable gain at either low frequency, passband frequency and high frequency band is presented. The gain at each of these frequency bands is controlled by a capacitor bank. This universal second order switched-capacitor filter employs 3 operational amplifiers, 3 capacitor banks and some additional ...

Class 2 ceramic capacitors, such as X7R, have relatively high energy density compared to Class 1 ceramic capacitors. However, they experience changes due to aging, temperature, and electric field. The measured X7R capacitance drop is 1%–2% per decade hour due to aging, 18% due to a temperature change from 25 °C to 125 °C, and 75% due to an applied ...
