  • Error-free startup of low phase noise oscillators
    Patent number: 8164392
    Abstract: An isolation switch is used to isolate the output of an oscillator, during startup of the oscillator, from the circuitry that uses the periodic signal generated by the oscillator. In one implementation, a device may include an oscillator to generate a periodic signal and a switch connected to receive an output of the oscillator. The switch may include a control input that controls whether the switch is in an open or closed state. Switch control circuit may control the switch so that the switch is in an open state during startup of the oscillator and the switch is in a closed state thereafter.
    Type: Grant
