摘要： A layout of a MOSFET current driver is disclosed which improves the fabrication yield and the current drive capability over that of the prior art while keeping the layout area the same as the prior art. In this design, the gate is laid out to have a lateral serpentine pattern rather than a vertical serpentine pattern to create a larger gate in order to improve the current drive capability. In addition, the contacts for the drain and the contacts for the source are removed from the gate layout area which facilitates condensing the gate layout and increasing the size of the gate. Also, this design has only two metal strips: one for the drain and one for the source of the MOSFET current driver. The two metal strips substantially overlap the serpentine patterned gate. Having only two metal strips reduces the spaces between the metal strips to one space thereby reducing the probability of having a short or a defect and improving the fabrication yield.
摘要翻译：公开了MOSFET电流驱动器的布局，其提高了现有技术的制造产量和电流驱动能力，同时保持布局面积与现有技术相同。在这种设计中，门被布置为具有侧向蛇形图案，而不是垂直的蛇形图案以产生更大的栅极，以便提高电流驱动能力。此外，用于源极的漏极和触点的触点从栅极布局区域移除，这有利于栅极布局的集中和增加栅极的尺寸。此外，该设计只有两个金属条：一个用于漏极，一个用于MOSFET电流驱动器的源极。两个金属条基本上与蛇形图案化的栅极重叠。只有两个金属条将金属条之间的空间减小到一个空间，从而减少了短或缺陷的可能性并提高了制造成品率。

摘要： The ink in an ink jet is sensed by a capacitor, one plate of which is coupled to ground through the ink. The absence of ink will appear as a decreased amount of capacitance. In this case the charge of the capacitor will leak off faster, and a sample and hold circuit can sense this to output a signal indicating the absence of ink. The charging signal can either be generated on the chip, which is made from silicon, or can be supplied to the chip. The number of pins on the chip taken for this sensing function can be minimized by multplexing the states of signals supplied to the chip for other purposes to generate the necessary signals to control and operate this sensor.

摘要： An acoustic inkjet printhead utilizes a pulse width modulation to control droplet size or ejection velocity. An individual control pulse controls the duration and the time a RF signal is applied to each transducer. To modify the RF signal of each transducer, the pulse width of each control signal can be modified according to a predetermined correction data. The rising edge of the control data is delayed according to the correction data while the falling edge is kept the same.

摘要： A method is provided that includes providing a mold on a temporary substrate, e.g., a sapphire substrate. Next, a material such as PZT paste is deposited into the mold. Then, the mold is removed to obtain elements formed by the mold. The formed elements will then be sintered. After sintering, electrode deposition is optionally performed. The sintered elements are then bonded to a final target substrate and released from the temporary substrate through laser liftoff. Further, electrodes may also be optionally deposited at this point.

摘要： An electronic circuit is utilized to correct scan non-linearity of a raster output scanner. The circuit modulates a clock frequency to match a scan linearity error profile. Because it is a separate circuit, the exiting closed-loop clock generator does not need to be modified. The correction circuit synchronizes itself with the clock signal using a counter/subtractor phase detector, which ensures that the phase and frequency of the internal clock matches the phase and frequency of the master.

摘要： An electronic driver circuitry for an RF switch diode used in Acoustic Ink Jet Printing (AIP) systems is disclosed The electronic driver circuitry consists of a PMOS transistor and a poly resistor used to control the on/off states of the RF switch diode wherein the drive current for the RF switch diode is the same as the current in the PMOS transistor. To compensate for undesirable variations in the RF switch diode, the driver circuitry is designed such that the current in the PMOS transistor is adjusted in an opposite direction to cancel the unwanted variations.
