A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

In this paper, a dual loop PLL with short locking time, low power consumption and low reference spur is presented. The output frequency and reference frequency of the designed circuit are 3.2 GHz and 50 MHz, respectively, aimed to WiMAX applications. In the proposed circuit in locked state, some parts of the circuit could be powered off, to reduce overall power consumption. Phase detection in t...

We proposed a new three-way DNA junction-driven strand displacement mode and fabricated an aptamer-based label-free fluorescent sensing platform on the basis of this mechanism. Assembling the aptamer sequence into the three-way DNA junction makes the platform sensitive to the target of the aptamer. A label-free signal readout method, split G-quadruplex enhanced fluorescence of protoporphyrin IX...

Histone ubiquitylation is a prominent response to DNA double-strand breaks (DSBs), but how these modifications are confined to DNA lesions is not understood. Here, we show that TRIP12 and UBR5, two HECT domain ubiquitin E3 ligases, control accumulation of RNF168, a rate-limiting component of a pathway that ubiquitylates histones after DNA breakage. We find that RNF168 can be saturated by increa...

This study was conducted in Mouteh grinding circuit. Mouteh gold processing plant is located in Esfahan province,center of Iran, close to Mouteh open pit mine. One of the main problems in this circuit is low efficiency grinding operation. In this study, first grinding circuit and its performance parameters are evaluated. Laboratory and corrected operating Bond work index subsequently were calcu...

1 Abstract Today most VLSI circuits are built in silicon using CMOS transistors. Developments in design automation and process fabrication have resulted in the progressive increase of the number of transistors per chip and decrease in the size of the transistors. But transistor designers are fast approaching fundamental physical barriers to further size reduction. Thus engineers are looking at ...
