  • Oscillator with improved parameters variation tolerance
    Patent number: 6965273
    Abstract: A design for an inverting delay component of an oscillator is disclosed, which enables the oscillator to be more tolerant of parameter variations. This increased parameter variation tolerance allows the KVCO of the oscillator to vary less between the worst case scenario (where the components of the oscillator meet minimum specifications) and the best case scenario (where the components meet the maximum specifications). This in turn means that the worst case KVCO value will be significantly smaller than in the prior art. By using a significantly smaller KVCO value, the jitter experienced at the output of the oscillator will be substantially reduced. Thus, this design enables a low-jitter oscillator to be realized.
