Abstract—In this paper, a novel dual-band RF-harvesting RF-DC converter with a frequency limited impedance matching network (M/N) is proposed. The proposed RF-DC converter consists of a dual-band impedance matching network, a rectifier circuit with villard structure, a wideband harmonic suppression low-pass filter (LPF), and a termination load. The proposed dual-band M/N can match two receiving...

A sophisticatedly designed polyelectrolyte diode was fabricated on a microchip and exhibited well-defined nonlinear rectifying behavior. Multiple polyelectrolyte diodes were integrated on a microchip to produce a variety of logic gates based on ionic circuits. By employing a fluorescent dye, the polyelectrolyte micro plugs also acted as optical indicators displaying the input signals applied to...

We actively stabilize the harmonic oscillation frequency of a laser-cooled atomic ion confined in a radiofrequency (rf) Paul trap by sampling and rectifying the high voltage rf applied to the trap electrodes. We are able to stabilize the 1 MHz atomic oscillation frequency to be better than 10 Hz or 10 ppm. This represents a suppression of ambient noise on the rf circuit by 34 dB. This technique...

This paper presents the design, implementation and characterization of a rectenna array for wireless powering of sensor electronics for airframe fatigue detection. The rectenna aperture is powered 5 minutes at a time during inspection with a requirement of ±15V at 100mW. The maximum incident RF power is 10mW/cm. A single rectenna element at this incident power density has an output power of 5 m...

In his seminal paper, Chua presented a fundamental physical claim by introducing the memristor, "The missing circuit element". The memristor equations originally supposed to represent a passive circuit element because, with active circuitry, arbitrary elements can be realized without limitations. Therefore, if the memristor equations do not guarantee that the circuit element can be realized by ...

A compact and highly efficient unidirectional DC–DC converter is required as a battery charger for electrical vehicles, which will rapidly become widespread in the near future. The single active bridge (SAB) proposed simple high-frequency isolated converter, comprised of an H-bridge primary side, high frequency transformer, rectifying secondary diode output circuit. This paper presents novel, u...

Remotely driven smart actuator technology by microwave is attractive since it simplifies and reduces the complexity weight of remote system. A rectifying antenna (rectenna) array receives converts power into DC for actuators, collected from rectenna should be accurately allocated distributed to each actuator. In this research, a new distribution (PD) logic circuit studied control an effectively...
