Abstract
An integrated circuit including a phase-locked loop (PLL) circuit responsive to a voltage controlled oscillator (VCO) frequency band selection circuit that provides automatic frequency band selection in real time to account for run-time variations, such as power supply and temperature variations over time. The PLL includes a charge pump and an LC tank circuit that provides the automatic frequency band selection based on a VCO control voltage signal supplied by the charge pump.
