    Abstract: A voltage generating circuit including a pre-driving unit and a voltage generating unit is provided. The pre-driving unit receives an oscillation signal and enhances a driving capability of the oscillation signal to generate a pre-driving signal. The voltage generating unit receives an input signal and the pre-driving signal, and generates an output signal according to the input signal and the pre-driving signal. The voltage generating unit generates a voltage signal according to the pre-driving signal. One of the pre-driving unit and the voltage generating unit adjusts a slew rate or a ringing component of the voltage signal by using the pre-driving signal. A pre-driving signal generating module for driving a voltage generating circuit is also provided.

  • Patent number: 9785192
    Abstract: Described in this disclosure is a surface configured to break down deposits thereon. The surface may include breakdown structures, oleophilic structures, and hydrophilic structures. The oleophilic structures and hydrophilic structures are configured to disperse a deposit, such as fingerprint residue, to the breakdown structures. This dispersion increases the surface area of the deposit with respect to the breakdown structures, increasing the contact area between the two. The breakdown structures modify the deposit physically, chemically, or both, such that fragments are distributed into the ambient environment. The surface may be applied to portable electronic devices.
