Abstract: An LC-VCO includes a multivibrator which outputs a frequency signal, a fine tuning circuit which tunes the frequency signal by a first amount, a coarse tuning circuit which tunes the frequency signal by a second amount, and a control circuit which controls the fine and coarse tuning circuits. The coarse tuning circuit is formed from one or more capacitive arrays and the fine tuning circuit is formed from one or more varactors. The capacitive arrays are preferably controlled by a digital signal, where each bit selectively couples a respective capacitor to the multivibrator. An analog signal controls the value of the varactors. The capacitive arrays and varactors charge and discharge an inducator in the multivibrator to tune the frequency signal. The VCO may be incorporated within a phase-locked loop, where the capacitors may be assigned different weight and/or redundancy values to tune an output frequency signal. In one embodiment, coarse tuning and lead-lag detection is performed more accurately to allow the size of the varactors to become significantly reduced compared with other circuits which have been proposed.

Abstract: A voltage-controlled oscillator including an active oscillator circuit, an inductor, and capacitive circuits is disclosed. The capacitive circuits are selectively turned on and off to control the frequency of the voltage-controlled oscillator. Particularly, the inductor and the capacitors in the capacitive circuits form LC circuits that provide feedback to the active oscillator circuit. To avoid damage to the switches in the capacitive circuits, the capacitive circuits further comprise resistors. The resistors can be configured in several different ways so that the voltage-controlled oscillator can have a high degree of reliability, and a wide tuning range with constant phase noise performance.

Abstract: The invention relates to an antistatic silicone release film having a layer coated with an antistatic silicone release composition, and, used for semiconductors, electronics and display devices while addressing problems of static electricity generated when a general release film is separated from adhesive or an adhesive layer, and of contamination by such static electricity that causes critical product defects. The invention also relates to an antistatic silicon release film that can reduce product contamination caused by static electricity in peeling the film from adhesive or an adhesive layer, and achieves close adhesion between a substrate and a coated layer because of no interruption in curing a release layer, and also thereby has a stable release property.
