A gain-compensated switched capacitor integrator
1998 Midwest Symposium on Circuits and Systems (Cat. No. 98CB36268), 2002A topology of switched capacitor integrator with gain compensation is proposed. It employs the same input as in the integrating phase during the calibration cycle to compensate for the integrating pole error due to the finite gain of the op-amp, and it eliminates the need of a "slow motion input" requirement.

Noise optimization of switched capacitor integrator
2015 IEEE International Conference on Electron Devices and Solid-State Circuits (EDSSC), 2015The paper presents a method of noise optimization for a type of classical switched-capacitor(SC) integrators to design the distribution plan of capacitors in a specific layout area. The OP utilized in the SC integrator is a two-stage OP. Thus there are three significant capacitors, two of which are sampling capacitors and one of which is the ...

Low‐sensitivity switched‐capacitor integrators
Electronics and Communications in Japan (Part I: Communications), 1987AbstractThe integrated circuit switched‐capacitor filter (SCF) has the merits that the temperature dependence and the effect of aging are small. To utilize these features, it is important to design the low element‐sensitivity to realize the initial characteristics with a high accuracy.

Predictive correlated double sampling switched-capacitor integrators
1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology (Cat. No.98EX196), 2002This paper explores predictive correlated double sampling (CDS) as a means of achieving good linearity and low power dissipation in switched-capacitor (SC) integrators. The technique reduces the effect of the open-loop nonlinearity characteristic of an amplifier, thereby allowing the utilization of single-stage low-gain structures.

High-Gain-Integrated Switched Capacitor Indirect Matrix Converter
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019An ultrasparse matrix converter (USMC) is a derived form of an indirect matrix converter having a less number of switches. Even though it has unidirectional power flow capability, it is a quite appropriate candidate for specific applications, such as wind-energy systems, electrohydrostatic actuators, variable speed drives, and so on.

Novel switched-capacitor integrator for high-frequency applications
IEE Proceedings G Circuits, Devices and Systems, 1989A discrete integrator for switched-capacitor (SC) filter applications is developed. The proposed integrator is generated from an optimal linear combination of the lossless discrete integrator (LDI) and the bilinear discrete integrator, and therefore it is called the composite discrete integrator (CDI).

Efficient design of integrated switched-capacitor decimation filters
IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 2000The infinite-impulse response (IIR) switched-capacitor (SC) decimation filter scheme proposed in this brief is based on the polyphase decomposition of an Mth band IIR low-pass filter, and uses first- and second-order all-pass SC filters as basic building blocks, operating at the lower sampling rate, resulting in reduced power consumption, capacitance ...
