Present handheld devices like Smart phones, can be charged wirelessly using new energy harvesting circuit technique through using the traditional wireless technologies. In this case, Bluetooth with a charging circuit enables a short-range wireless charging of a mobile handheld. This paper present the overview of new process of charging and structure of power charging based on Scotty diode with ...
A novel version of chaotic Colpitts oscillator is described. Instead of a linear loss resistor, it includes an extra inductor and a diode in the collector circuit of the transistor. The modified circuit in comparison with the common Colpitts oscillator may generate chaotic oscillations at the fundamental frequency f∗ noticeably closer to the threshold frequency fT of the employed bipolar juncti...
This paper describes the design of a high speed semiconductor laser diode driver designed for driving 500 mW to 1.5 W diodes at full optical power modulation up to frequencies of 10 MHz. The duty cycle of the modulation may be varied. A switching power-converter based current source allows a higher power delivery efficiency to the diode than in previous designs, allowing for a more modest power...
Precomputation is a recently proposed logic optimization technique which selectively disables the inputs of a sequential logic circuit, thereby reducing switching activity and power dissipation, without changing logic functionality. In this paper, we present new precomputation architectures for both combinational and sequential logic and describe new precomputation-based logic synthesis methods...
An asynchronous circuit, or self-timed circuit, is a sequential digital logic circuit which is not enabled by a global clock signal. Instead of that, they often use signals that indicate completion of operations and instructions, specified by handshaking or simple data transfer protocols. This type is contrasted with a synchronous logic circuit where changes to the output signal values are trig...

The electron beam assisted chemical vapor deposit ion of silicon nitride anti-reflection coatings onto thin film CdS/CuInSe2 solar cells and the resultant effects on their performance are reported. In some cases large increases in the short circuit current, open circuit voltage and fill factor were observed. The present results are explained by the usual index matching anti-reflection mechanism...
A pixel design for active matrix organic light emitting diode (AM-OLED) displays employing hydrogenated amorphous silicon (a-Si:H) thin film transistors (TFTs) is proposed. The proposed pixel circuit, which composed of five TFTs and one capacitor, could compensate the shift of threshold voltage of OLED as well as the threshold voltage of a-Si:H. We fabricated the pixel circuits on the glass sub...
The impact of gate oxide degradation of a single pMOSFET on the performance of the CMOS NOR logic circuit has been examined using a switch matrix technique. A constant voltage stress of -4.0V was used to induce a low level of degradation to the 2.0nm gate oxide of the pMOSFET. Characteristics of the CMOS NOR logic circuit following gate oxide degradation are analyzed in both the DC and V-t doma...
A novel diode-checkerboard test structure (DCTS) is presented to determine open circuit defects and short circuit defects as well as to investigate the 3D-influence of underlying topography. The arrangement of the DCTS in a standard boundary pad frame and the digitally measuring procedure evaluate a fast and effective (efficient) online process characterization. The precise defect detection and...
