Voltage controlled oscillator band switching system

A band switching method, comprising:

• generating 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;
• generating a clock pulse in response to said positive signal;
• and
• disabling band switching of said voltage controlled oscillator when a lock condition is detected and said loop filter voltage comprises a voltage between said maximum tuning voltage and said minimum tuning voltage.

A system, comprising:

• an antenna;
• and
• an integrated circuit coupled to said antenna, said integrated circuit comprising a band switching apparatus, said band switching apparatus comprising:
• a reference generation and comparison module to 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;
• a clock pulse generation module to generate a clock pulse in response to said positive signal;
• and
• a counter and gating module to disable band switching of said voltage controlled oscillator when a lock condition is detected and said loop filter voltage comprises a voltage between said maximum tuning voltage and said minimum tuning voltage.
