An organic thin film transistor, a method of fabricating the same, and an organic light emitting diode display device having the same. The device includes a loudspeaker enclosure including a first acoustic port, and an acoustic driver, mounted in the loudspeaker enclosure. This micromachined LC-tank apparatus is incorporated with CMOS transistor circuitry in order to realize a digital, tunable, low phase jitter, and low power clock, or time base, for synchronous integrated circuits. The inner magnetic portion and the outer magnetic portion are concentric and aligned with the eccentric shaft portion.
