A novel compact rectifier for dual-band operation in the RF energy harvesting is presented. The circuit comprises a 4th order dual-band impedance matching and a single-series circuit with one double diode, both are integrating into a compact shape to occupy a small area of 30 × 35 mm. The merit of the proposed rectifier circuit is that it can be extended to n number of the frequency band by usi...

Short-circuit evaluation denotes the semantics of propositional connectives in which the second argument is evaluated only if the first argument does not suffice to determine the value of the expression. In programming, short-circuit evaluation is widely used. A short-circuit logic is a variant of propositional logic (PL) that can be defined by short-circuit evaluation and implies the set of co...

We study the origins of period doubling and chaos in the driven series resistor-inductor-varactor diode (RLD) nonlinear resonant circuit. We find that resonators driven at frequencies much higher than the diode reverse recovery rate do not show period doubling. Models of chaos based on the nonlinear capacitance of the varactor diode display a reverse-recovery-like effect, and this effect strong...

As solar energy costs continue to drop, the number of large-scale deployment projects increases, and the need for different analysis models for photovoltaic (PV) modules in both academia and industry rises. This paper proposes a modified equivalent-circuit model for PV modules. A PV module comprises several series-connected PV cells, to generate more electrical power, where each PV cell has an ...

Hybrid nanoelectronics consisting of nanodevice crossbars on top of CMOS backplane circuits is emerging as one viable option to sustain Moore's law after the CMOS scaling limit is reached. One main design challenge in such hybrid nanoelectronics is the interface between the highly dense nanowires in nanodevice crossbars and relatively coarse microwires in the CMOS domain. Such an interface can ...

Nowadays renewable micro-energy harvesting system is becoming attractive, because this energy is free which leads to reduce energy cost. Piezoelectric is one of the common energy harvesting systems. Generally, the output of a piezoelectric transducer is a small AC voltage and its power is also small. As a result, the convertion of this low AC voltage into DC voltage by using rectifier diode is ...

In this paper, a new high-speed circuit technique called differential cascode voltage switch with pass-gate (DCVSPG) logic tree is presented. The circuit technique is designed using a pass-gate logic tree in DCVSPG instead of the nMOS logic tree in the conventional DCVS circuit, which eliminates the floating node problem. By eliminating the floating node problem, the DCVSPG becomes a new type o...

Several realizations of Chua’s circuit have been proposed in the literature. The methodologies used in these realizations can be divided into two basic categories. In the first approach, a variety of circuit topologies have been considered for realizing the nonlinear resistor, NR in Chua’s circuit. The main idea in the second approach related to the implementation of the circuit is an inductorl...

The implementation of a low power logic based asynchronous circuit with the help of power gated logic. In asynchronous power gated logic (APL) circuit, each pipeline stage was incorporated with efficient charge recovery logic (ECRL) gate; handshake controller and partial charge reuse (PCR) mechanism. The main objective was, to provide a new lower power solutions using power gating (PG) for very...

Nanowires represent a promising class of materials for exploring new concepts in solar energy conversion. Here we report the first experimental realization of axial modulation-doped p-i-n and tandem p-i-n(+) -p(+)-i-n silicon nanowire (SiNW) photovoltaic elements. Scanning electron microscopy images of selectively etched nanowires demonstrate excellent synthetic control over doping and lengths ...
