Microwave and Millimeter-wave Rectifying Circuit Arrays and Ultra-wideband Antennas for Wireless Power Transmission and Communications. (May 2007) Yu-Jiun Ren, B.S., National Chung-Hsing University; M.S., National Chiao-Tung University Chair of Advisory Committee: Dr. Kai Chang In the future, space solar power transmission and wireless power transmission will play an important role in gathering...

This paper is focused on a wireless energy harvesting system using a rectifying antenna (rectenna). The proposed device consists of a wideband cross-dipole antenna, a microwave low-pass filter and a doubling rectifying circuit using Shottcky diodes as rectifying elements. Previously, a few of wideband rectennas have been investigated at 1.7 to 2.5 GHz. The originality of this paper is on the ne...

Rectifying electrical synapses are commonplace, but surprisingly little is known about how rectification alters the dynamics of neuronal networks. In this study, we use computational models to investigate how rectifying electrical synapses change the behavior of a small neuronal network that exhibits complex rhythmic output patterns. We begin with an electrically coupled circuit of three oscill...

To solve the crosstalk problem when integration density of resistive random access memory (RRAM) devices increase, RRAM with self-rectifying function is required. Herein, Au/10 nm Al 2 O 3 /heavily doped p-type Si (p++-Si) structure was fabricated, and bipolar switching effect were investigated. A rectification 6.5 × 10 under ±5 V at low-resistive state (LRS) observed. The rectifying explained ...

One of the difficulties with PWM switching converters is high switching loss and electromagnetic interference due to switching at non-zero voltage and current, which limits the operating frequency. In order to reduce the converter volume and weight (by increasing the frequency) and reducing switching losses, zero voltage and current switching methods are recommended. In this paper, four main ze...
