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 ...

Ring amplifiers for switched-capacitor circuits
2012 IEEE International Solid-State Circuits Conference, 2012In this paper the fundamental concept of ring amplification is introduced and explored. Ring amplifiers enable efficient amplification in scaled environments, and possess the benefits of efficient slew-based charging, rapid stabilization, compression-immunity (inherent rail-to-rail output swing), and performance that scales with process technology.

Analysis of switched-capacitor networks (SCN) based on capacitor - switch macromodels
IEEE Transactions on Circuits and Systems, 1985In this paper, we present a new method of analysis of switched-capacitor networks (SCN) based on the concept of capacitorswitch (CS) blocks. The combination of any capacitor and its related switches in the SCN is considered as an integral component and the nodes within the combination can be discarded.

In the last years the interest toward low-power low-voltage integrated systems has consistently grown due to the increasing importance of portable equipment and to the reduction of the supply voltage of modern scaled-down technology IC [1, 2]. In such systems, a number of analog functions can be efficiently implemented with SC technique which ensures ...

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 ...

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.

This chapter introduces SC circuits. A brief description is given for the main building blocks of a SC filter (operational amplifiers, switches, capacitors, and non-overlapping clock phases). A few examples of SC resistor emulation circuits are presented along with their equivalent resistance. Two examples of SC integrators are also shown, one with the

It is rare that a new discipline can be traced back to the publication of a single paper. Information theory is such a discipline. Another, although less dramatic, is the discipline of switched capacitors. In a 1977 paper by Hosticka, Broderson, and Grey of Berkeley University entitled “MOS Sampled-Data Recursive Filters Using State-Variable Techniques,

The elusive goal of the lossless charge transfer from one circuit node to another has been the main focus of analog sampled-data processing starting from the bucket brigade and CCD to switched-capacitor circuits. Opamp with capacitive feedback is the most accurate analog component that can sample and amplify signal with highest accuracy.
