Abstract
An apparatus, method, and system for voltage controlled oscillator band switching are described. A band switching apparatus may include a reference generation and comparison module, a clock pulse generation module, and a counter and gating module. The reference generation and comparison module may generate a positive signal based on a comparison of a loop filter voltage associated with a voltage controlled oscillator to a maximum tuning voltage and a minimum tuning voltage. The clock pulse generation module may generate a clock pulse in response to the positive signal. The counter and gating module may disable band switching of the voltage controlled oscillator when a lock condition is detected and the loop filter voltage is between the maximum tuning voltage and the minimum tuning voltage. Other embodiments are described and claimed.
