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.....

Color liquid crystal displays (LCD) are usually made by putting color filters onto the individual pixels. These color filters are resins with color pigments. Full color displays can be made by a combination of the red, green and blue primary colors. This coloring scheme is the predominant technology.....

Frequency-divider circuit is a key building block of phase-locked-loop (PLL) and frequency synthesizer (FS) circuits, which are required for all data communication and telecommunication systems. However, the failure of frequency-divider circuits functioning at low-voltage high-frequency operation is.....

Television and video programming are now available by cable systems. However, the difficulty is that telecommunication services are commonly provided through a network of optical fibre cables that extend as far as the basement of a building, and then for signals to be carried to individual users by .....

Thin-film transistors (TFTs) are used in the construction of active-matrix devices like liquid-crystal displays (LCDs), organic light emitting diode (OLED) displays, and image sensors. TFTs based on amorphous silicon suffer from low operating speed and lack of a p-type device, making it difficult to.....
