发明名称 Self-calibrated wide range LC tank voltage-controlled oscillator (VCO) system with expanded frequency tuning range and method for providing same
摘要 The present invention is a self-calibrating, dual-band, wide range LC tank Voltage Controlled Oscillator (VCO) system. The system may include a first Voltage-Controlled Oscillator (VCO) and a second Voltage-Controlled Oscillator (VCO). The system may further include a calibration engine. The calibration engine may be configured for being connectable to at least one of the first VCO or the second VCO. The calibration engine may further be configured for automatically establishing/providing a VCO fix capacitor band code setting and a gear control setting for selectively activating or inactivating the first VCO and/or the second VCO. The calibration engine may be further configured for automatically comparing a VCO control voltage of the system to an allowable control voltage range for the system and may be further configured for automatically adjusting the VCO fix capacitor band code setting and/or the gear control setting when the VCO control voltage falls outside of the allowable control voltage range.
