2. CAPACITIVE SOLUTIONS This paper reviews differential implementations of threshold logic gates, detailing two classes of solutions: capacitive (switched capacitor and floating gate), and conductance/current. The concept underlying capacitive TLGs is the use of an array of capacitors to implement the weighted sum of inputs. The idea was introduced as early as 1966 [6]. Capacitive TLGs can be c...

This study compares ripple port, stacked switched capacitor, and capacitive energy storage architectures for active power decoupling, comparing the number of components, performance, density, DC-link capacitor reduction, efficiency, frequency operation to highlight their main benefits drawbacks single-phase grid-connected applications. The overview reveals equivalent effective density without e...

Multi-level inverters (MLIs) with switched capacitors are becoming popular due to their utilization in AC high-voltage applications as well the field of renewable energy. To achieve required magnitude output voltage, capacitor (SC) technique employs a lesser number DC sources accordance voltage across capacitor. Designing an efficient high-gain MLI fewer and switches needs rigorous effort. This...

A 1-V 10.7-MHz fourth-order bandpass delta-sigma modulator using two switched opamps (SOPs) is presented. The 3/4 sampling frequency and the double-sampling techniques are adapted for this modulator to relax the required clocking rate. The presented modulator can not only reduce the number of SOPs, but also the number of capacitors. It has been implemented in 0.25m 1P5M CMOS process with MIM ca...

This article applies the artificial bee colony algorithm to define and allocate static shunt capacitors along radial distribution networks. The objective function is adapted to maximise net yearly savings and to enhance the overall system static voltage stability index with weighting and magnifying factors. Load variations have been considered to optimally size the fixed and switched capacitors...

In this paper, a CMOS custom Integrated Circuit featuring a multi-stage Universal Switched-Capacitor (SC) Filter is Introduced. The network is based on the Generalized Immittance Converter (GIC) configuration, known for its excellent passive and active sensitivities. CMOS switches were used for elements relocation and are digitally controlled to select and realize different filter topologies. S...

Power electronic converter systems for applications such as telecom, automotive, and space can have dc voltage buses that are backed up with batteries or super-capacitors. These batteries or super-capacitors are connected to the buses with bidirectional dc–dc converters which allow them to discharged or charged, depending on the operating conditions. Bidirectional dc–dc converters may be isolat...

Accurate capacitance matching is one of the main design issues in switched-capacitor (SC) filters. Using identical unit capacitors in parallel to implement each filter capacitor, combined with a careful layout design, can provide an accuracy of 0.1% in the filter coefficients. The disadvantage of this technique is the fact that it can be directly applied only if the coefficients can be expresse...

This study proposes a method which consists of High step up DC-DC converter with a coupled inductor for distributed generation system. Theoretically the conventional boost converter provides high step up voltage gain but in practical it is limited by reverse recovery problem of diode, effective series impedance of inductors and capacitors and switching losses. High charged current and conductio...

Due to concerns, such as global warming and depletion of fossil fuels, countries are forced integrate energy storage devices (ESSs) renewable sources (RESs), photovoltaic (PV) systems, wind turbines fuel cells, into their power networks. Here, a new high gain DC–DC converter with step-up/down ability is proposed for modern applications. Since this provides variable voltage gain, it can be emplo...
