Method And System For Precise Temperature And Timebase PPM Error Estimation Using Multiple Timebases

A system for wireless communication, the system comprising:

• one or more circuits for use in an electronic device comprising a plurality of timebases, said one or more circuits being operable to:
• measure a temperature corresponding to said plurality of timebases;
• compare frequencies of said plurality of timebases at said measured temperature corresponding to said plurality of said timebases;
• generate a more accurate reading of said temperature corresponding to said plurality of timebases based, at least in part, on said measured temperature and said frequency comparison of said plurality of timebases;
• and
• calibrate said plurality of timebases utilizing said generated more accurate reading of said temperature corresponding to said plurality of timebases.

A system for electronic clock signals, the system comprising:

• an integrated circuit that utilizes a plurality of timebases, said integrated circuit being operable to:
• measure a temperature corresponding to said plurality of timebases;
• compare frequencies of said plurality of timebases at said measured temperature corresponding to said plurality of said timebases;
• generate a more accurate reading of said temperature corresponding to said plurality of timebases based, at least in part, on said measured temperature and said frequency comparison of said plurality of timebases;
• and
• calibrate said plurality of timebases utilizing said generated more accurate reading of said temperature corresponding to said plurality of timebases.
