| 20080297207 | DOUBLE DATA RATE TRANSMITTER AND CLOCK CONVERTER CIRCUIT THEREOF - A double data rate (DDR) transmitter and a clock converter circuit are provided. The clock converter circuit includes a first logic circuit and a second logic circuit. The first logic circuit receives a clock signal as a trigger signal, performs a sequential logic operation based on the clock signal, and outputs a result of the sequential logic operation. The second logic circuit is coupled to the first logic circuit. The second logic circuit performs a combinational logic operation based on the output of the first logic circuit and outputs a result of the combinational logic operation as a converted signal. The converted signal has the same waveform and frequency as those of the clock signal, and the phases of the clock signal and the converted signal are the same or only slightly different. | 12-04-2008 |

| 20090244935 | INVERTER APPARATUS WITH ADAPTABLE VOLTAGE-TO-FREQUENCY CONTROL - An inverter apparatus has an adaptable high-resolution voltage-to-frequency (V/f) control. The inverter apparatus receives an analog input signal and includes a first circuit, a second circuit, a third circuit, and a micro-controller unit. The first circuit processes a small-signal portion of the analog input signal with a larger voltage gain. The second and the third circuit both processes large-signal portions of the analog input signal with smaller voltage gains respectively. The three processed analog input signals of the first, the second, and the third circuits are converted into three digital output values respectively. The largest digital output value is selected by the micro-controller unit and supplied to a frequency operation unit for generating a corresponding output frequency. | 10-01-2009 |

| 20090137113 | Method for fabricating a Microstructure - A method for fabricating a microstructure is to form at least one insulation layer including a micro-electro-mechanical structure therein over an upper surface of a silicon substrate. The micro-electro-mechanical structure includes at least one microstructure and a metal sacrificial structure that are independent with each other. In the metal sacrificial structure are formed a plurality of metal layers and a plurality of metal via layers connected to the respective metal layers. A barrier layer is formed over an upper surface of the insulation layer, and an etching stop layer is subsequently formed over a lower surface of the silicon substrate. An etching operation is carried out from the lower surface of the silicon substrate to form a space corresponding to the micro-electro-mechanical structure, and then the metal sacrificial structure is etched, thus achieving a microstructure suspension. | 05-28-2009 |
