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...

Misalignment is a common issue in wireless power transfer systems. It shifts the resonant frequency away from operating that affects flow and efficiency charging station to load. This work proposes novel capacitive (CPT) using an 8-plate multi-resonant coupling minimize effect of misalignments. A single-active switch class-E2 converter utilized achieve multi-resonance through selection differen...

In this work, activated carbon (AC) derived from biomass wastes was implemented as electrode materials in supercapacitor application. This study has adopted rubber seed shell (RSS) wastes to derive AC via pyrolysis process. Meanwhile, reduced graphene oxide (rGO) was used as an additive material in order to study the effect of the rGO in capacitive behavior. The synthesized rGO was successfully...

The inductively coupled RF discharge is known to exhibit two modes of operation depending on the level of incident power. Dominant capacitive coupling (E-mode discharge) occurs at low-power level while at high power, dominant inductive coupling (H-mode discharge) is obtained. In this work, we investigate the characteristics of the E-mode and H-mode discharges generated in a planar coil inductiv...

The current study examines the feasibility of placing a piezoelectric membrane or &&eel'' in the wake of a blu! body and using the von KaH rmaH n vortex street forming behind the blu! body to induce oscillations in the membrane. The oscillations result in a capacitive buildup in the membrane that provides a voltage source that can be used, for example, to trickle-charge a battery in a remote lo...

A detailed description of the tunneling processes within Aharonov-Bohm (AB) rings containing two-dimensional quantum dots is presented. We show that the electronic propagation through the interferometer is controlled by the spectral properties of the embedded dots and by their coupling with the ring. The transmittance of the interferometer is computed by the LandauerBüttiker formula. Numerical ...

Various DC-SQUID sensor configurations were developed for use in our 19-channel neuromagnetometer. Apart from the standard type, resistively and inductively shunted SQUIDs were made, allowing for a large screening factor p (>l). In this way signal coupling from the pick-up coil to the SQUID is facilitated and capacitive coupling between the input coil and the SQUID washer can be decreased. The ...

The element-by-element finite element method (EBEFEM) combined with the preconditioned conjugate gradient (PCG) technique is employed in this paper to calculate the coupling capacitances of multi-level high-density three-dimensional interconnects (3DIs). All capacitive coupling 3DIs can be captured, with the effects of all geometric and physical parameters taken into account. It is numerically ...

Electric machines are driven nowadays by static system popularly known as soft starter. This paper describes a thyristor based static frequency converter (SFC) to run a large synchronous machine installed at a short circuit test laboratory. Normally a synchronous machine requires prime mover or some other driving mechanism to run. This machine doesn’t need a prime mover as it operates in dual m...
