摘要： An on-chip inductor structure includes a conductive inductor coil and a helical ferromagnetic inductor core that is formed to wrap around the conductive coil. The coil is space-apart from the ferromagnetic core by intervening dielectric material. The helical core structure includes at least one magnetic gap lithographically formed in the core.

摘要： A method for determining consistency of a permeability of a ferromagnetic material in integrated circuits in which a test strip of the subject ferromagnetic material is included for testing with an impedance measurement instrument, such as an inductance-capacitance-resistance (LCR) meter, with which the resistance of the strip of ferromagnetic material over a range of measurement signal frequencies is determined based upon the measured impedance values. The measured impedance values, measurement signal frequencies and selected permeability values are then used in numerical simulations to produce multiple resistance versus frequency curves each of which corresponds to one of the selected permeability values.

摘要： A wireless tire pressure sensing system based upon a Schrader valve design is provided. The system includes a valve body, a valve pin and a compression element for sealing engaging the valve body and the valve pin to maintain tire pressure. A pressure sensing device mounted within the valve body and connected to valve pin senses the pressure within the tire and provides its signal to the valve pin. The valve pin is adapted as a component of an antenna that transmits a wireless pressure signal to a remote receiver/transmitter mounted on the vehicle. The receiver/transmitter transmits a corresponding signal to a vehicle control system that generates a warning signal when the tire pressure is below a threshold safety value.

摘要： Improvements in the level of integration of a core buck and/or boost DC-DC voltage regulator sub-circuit lead to a lower manufacturing cost structure, an improved performance from lessened intrinsic parasitic resistance, a smaller die size and, thus, higher wafer yield. Further, by integrating certain components on-chip, the cost and complexity of the conventional hybrid circuit implementation is improved.

摘要： The radio frequency (RF) impedance of a metal trace at gigahertz frequencies is reduced by forming the metal trace to have a base region and a number of fins that extend away from the base region.
