Systems involving temperature compensation of voltage controlled oscillators |
摘要 |
Systems involving temperature compensation of voltage controlled oscillators are provided. In this regard, a representative system incorporates: a voltage controlled oscillator (VCO) having a tuning port and a phase-locked loop (PLL); and a temperature dependent voltage source. The VCO selectively exhibits one of a coarse tuning mode in which the temperature dependent voltage source is electrically connected to the VCO tuning port, and a locked mode in which the temperature dependent voltage source is not electrically connected to the VCO tuning port such that the PLL controls the frequency of the VCO.
