In this study, the noise voltage on the circuit installed in the frame caused by the ground potential variation and the influence of the resistance of the frame ground on the noise voltage on the circuit are discussed. It is concluded as a result of measurement and circuit simulation that the noise voltage gets lower as the grounding resistance becomes high and the capacitive coupling between t...

cuins2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  in  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. the effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  the nanostructures  were  characterized  by  means  of  ...

In this paper, a CMOS emulator circuit that can reproduce nanoscale memristive behavior is proposed. The proposed emulator circuit can mimic the pinched hysteresis loops of nanoscale memristor memory's current-voltage relationship without using any resistor array, complicated circuit blocks, etc. that may occupy very large layout area. Instead of using a resistor array, other complicated circui...

This paper presents a new circuit arrangement for a current-mode Wheatstone bridge that is suitable for low-voltage integrated circuits implementation.

For Common R or R-L load to apply arbitrary voltage, the bridge traditional inverters don’t have any difficulties by PWM method. However for driving some piezoelectric actuator, arbitrary voltage not a pulse but a steady voltage should be applied. Piezoelectric load is considered as R-C load and its voltage does not decrease even though the applied voltage decreases. Therefore it needs some spe...

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...
