In wireless applications, phase-locked-loop frequency synthesizers require very good phase noise performance in order to obtain a good signal-t-noise ratio for the desired signals even in the presence of very large nearby unwanted signals. Inside frequency synthesizers, thermal noise generated by th.....

Organic electroluminescent or organic light emitting diode (OLED) devices are light emitting devices that are based on the passage of current through one or multiple organic thin layers. This invention proposed a new method of treatment of the transparent conducting anode layer which will therefore .....

Electrorheological(ER) fluids are of high interest because potentially they can provide simple, quiet, and fast interfaces between electrical controls and mechanical systems. However, a problem with ER fluids to date is that the yield strength is too low for many practical applications. The main dra.....

Melatonin has been implicated in the regulation of a number of physiological processes and, thus, has been used in the treatment of various biological disorders. It is widely used in the treatment of chronobiological disorders such as seasonal affective disorders (SAD), primary and secondary insomni.....

Conventionally, frequency tuning is achieved by changing the capacitance of a tank using varactor. However, it is more power efficient to minimize the capacitance of the tank and adjust the inductance for frequency variation. Therefore, the need for a variable inductor arises.A novel integrated vari.....
