Us Patents

  • Regulated, Symmetrical Crystal Oscillator Circuit And Method

    view source
  • US Patent:
    7123113, Oct 17, 2006
  • Filed:
    Jun 11, 2004
  • Appl. No.:
    10/866510
  • Inventors:
    Aaron Brennan - Moscow ID,
    Jonathon Stiff - Beaverton OR,
    Mike McMenamy - Tensed ID,
  • Assignee:
    Cypress Semiconductor Corp. - San Jose CA
  • International Classification:
    H03B 5/36
    H03B 1/00
    H03L 1/00
    H03L 5/00
  • US Classification:
    331158, 331 74, 331116 FE, 331183, 331186
  • Abstract:
    An oscillator circuit is provided that is preferably a crystal oscillator, where voltage placed across the crystal is regulated. The regulated voltage or amplitude of the cyclical signal across the crystal is monitored and maintained through a regulation circuit that measures a peak voltage across the crystal. Once the peak voltage exceeds a predetermined setpoint value, then a controller within the regulation circuit will reduce a biasing current through an amplifying transistor within the amplifier coupled across the crystal input and output nodes. By regulating the biasing current, gain from the amplifier is also regulated so that unwanted non-linearities and harmonic distortion is not induced within the crystal to cause frequency distortion and unwanted modes of oscillation within the crystal. The amplifier is preferably symmetrical in that the amplifier sources and sinks equal current to reduce unwanted peaks at the negative or positive half cycles of the sinusoidal signal.
  • Oscillator Amplifier Circuit Operable To Provide Symmetric Current Limiting And Method Of Same

  • US Patent:
    7196586, Mar 27, 2007
  • Filed:
    Dec 10, 2004
  • Appl. No.:
    11/009816
  • Inventors:
    Jonathon Stiff - Beaverton OR,
    Aaron Brennan - Moscow ID,
  • Assignee:
    Cypress Semiconductor Corporation - San Jose CA
  • International Classification:
    H03F 3/04
  • US Classification:
    330311, 330298
  • Abstract:
    An amplifier circuit operable to provide symmetric current limiting. The amplifier circuit includes a common source amplifier for sourcing a current and receiving an voltage input, a current source, and a current limiting device coupled between the common source amplifier and the current source. The current limiting device is operable to limit the current sourced by the common source amplifier. A bias network coupled to the current limiting device biases the current limiting device. An output is coupled to the current limiting device. The amount of current that is sourced to the output of the amplifier circuit may be limited, such that current limiting is symmetrical.
  • Nonvolatile Programmable Crystal Oscillator Circuit

  • US Patent:
    7221233, May 22, 2007
  • Filed:
    Sep 24, 2004
  • Appl. No.:
    10/949176
  • Inventors:
    Aaron Brennan - Moscow ID,
    Mark Lugar - Moscow ID,
    Mike McMenamy - Tensed ID,
  • Assignee:
    Cypress Semiconductor Corp. - San Jose CA
  • International Classification:
    H03B 5/32
  • US Classification:
    331158, 331116 R
  • Abstract:
    According to embodiments of the invention, a nonvolatile memory such as a flash memory is used to configure a single die after packaging of the die has occurred. Thus, numerous applications may be supported by a single die or optimization within a given application may occur. According to embodiments of the invention, the nonvolatile memory may be accessed through a programming interface, and preferably, through a two-pin programming interface, to normalize parameters such as package parasitics, crystal variations, output dividers, output duty cycle, output edge rates, I/O configuration, and oscillator gain. According to an embodiment of the invention, an XO circuit configuration includes a nonvolatile memory and a stand-alone XO, where the XO circuit configuration does not require a PLL to synthesize a reference frequency produced by the XO.
  • Poly-Phase Frequency Synthesis Oscillator

  • US Patent:
    7332976, Feb 19, 2008
  • Filed:
    Feb 3, 2006
  • Appl. No.:
    11/347189
  • Inventors:
    Aaron Brennan - Moscow ID,
  • Assignee:
    Cypress Semiconductor Corporation - San Jose CA
  • International Classification:
    H03B 5/36
  • US Classification:
    331 45, 333172
  • Abstract:
    A frequency synthesis/multiplication circuit and method for multiplying the frequency of a reference signal. In one embodiment, multiple versions of the reference signal are generated having different phases relative to one another, and these multiple versions are combined to form an output signal having a frequency that is a multiple of the frequency of the reference signal.
  • Regulated Capacitive Loading And Gain Control Of A Crystal Oscillator During Startup And Steady State Operation

    view source
  • US Patent:
    7859355, Dec 28, 2010
  • Filed:
    Mar 22, 2006
  • Appl. No.:
    11/277185
  • Inventors:
    Aaron Brennan - Moscow ID,
    Mike McMenamy - Tensed ID,
  • Assignee:
    Cypress Semiconductor Corporation - San Jose CA
  • International Classification:
    H03L 5/02
  • US Classification:
    331183, 331 36 C, 331177 V, 331186
  • Abstract:
    An oscillator circuit and system are provided having a peak detector that can determine a peak voltage value from the oscillator. The peak voltage value can then be compared against a predetermined voltage value by a controller coupled to the peak detector. The comparison value is then used to change a bias signal if the peak voltage value is dissimilar from the predetermined voltage value. A variable capacitor or varactor can be formed from a transistor and is coupled to the oscillator for receiving the bias signal upon a varactor bias node. The bias signal is used to regulate the capacitance within the varactor as applied to the oscillator nodes. Another controller can also be coupled to the peak detector to produce a second bias signal if the peak voltage is dissimilar from a second predetermined voltage value. The second bias signal can then be forwarded into an amplifier having a variable gain to regulate the gain applied to the oscillator. The combination of a varactor and variable gain amplifier regulate the negative resistance applied to the resonating circuit during startup and steady state operations to ensure a relatively fast startup, and to maintain optimal loading and accurate steady state amplitude after startup has completed.
