1. An integrated tire pressure sensor system, comprising:

  • (a) one or more MEMS-based sensors, including a MEMS-based pressure sensor for sensing a pressure of a tire;

    (b) a MEMS-oscillator-based wireless signal transmitter for transmitting data generated by said MEMS-based pressure sensor, wherein said MEMS-oscillator-based wireless signal transmitter comprises;

    (i) a MEMS-oscillator-based resonator for generating a desired output frequency; and

    (ii) a fractional-N synthesizer to modify said desired output frequency of said MEMS-oscillator-based resonator; and

    (c) an asynchronous microcontroller;

    wherein said one or more MEMS-based sensors, said MEMS-oscillator-based wireless signal transmitter and said asynchronous microcontroller are integrated onto one or more chips in one or more packages.
