Differential voltage controlled oscillators are provided including a differential oscillator core, a first linear capacitor, a second linear capacitor, a first phase noise reduction device, and a second phase noise reduction device. The differential oscil...
|6496075||Automatic tuning of VCO|
A voltage controlled oscillator (VCO) is tunable over a wide frequency range while exhibiting low phase noise by dynamically switching between two or more voltage/frequency operating curves. Reference voltages establish switching thresholds for each opera...
