This patent application has not been assigned to a company or institution.
The following quote was obtained by the news editors from the background information supplied by the inventors: "Various types of electronic devices are commonly used nowadays. In this regard, electronic devices may be used by one or more users, for various purposes, both business and personal. Electronic devices may be mobile or non-mobile; may support communication (wired and/or wireless); and/or may be general or special purpose devices. Examples of electronic devices may comprise handheld mobile devices (e.g., cellular phones, smartphones, and/or tablets), computers (e.g., laptops, desktops, and/or servers), and/or other similar devices.
"In some instances, clock signals may be used in electronic devices, such as to drive and/or control operations (or timing thereof) of particular components or subsystems of the electronic devices. The electronic devices may comprise dedicated components, such as crystal oscillators, which may be utilized in generating clock signals. In this regard, crystal oscillators may be configured to generate electrical signals with a precise frequency based on mechanical resonance of vibrating crystals. The frequency of the electrical signals may be used to keep track of time, such as to enable providing precise and stable clock signals. It is important to ensure that crystals used in crystal oscillators are not damaged or degraded because of operations of the crystal oscillators.
"Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such approaches with some aspects of the present method and apparatus set forth in the remainder of this disclosure with reference to the drawings."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventor's summary information for this patent application: "A system and/or method is provided for a crystal oscillator with an electrostatic discharge (ESD) compliant drive level limiter, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.
"These and other advantages, aspects and novel features of the present disclosure, as well as details of illustrated implementation(s) thereof, will be more fully understood from the following description and drawings.
BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWINGS
"FIG. 1 is a block diagram illustrating an example of an electronic device comprising a crystal oscillator implementing a Pierce topology.
"FIG. 2 is a block diagram illustrating an example of crystal oscillator implementing a modified Pierce topology with clamp based drive level limiting.
"FIG. 3 is a block diagram illustrating an example of current flow in a modified Pierce crystal oscillator configured for crystal drive level limiting, during a positive electrostatic discharge (ESD) event.
"FIG. 4A is a flow chart that illustrates an example of clamping in a modified Pierce crystal oscillator, to limit crystal drive level, during normal operation.
"FIG. 4B is a flow chart that illustrates an example of clamping in a modified Pierce crystal oscillator, to limit crystal drive level, during a positive electrostatic discharge (ESD) event."
