For use in a tire pressure monitoring system, an initiator generator comprising:
- an oscillator/divider configured to generate an output signal in response to a switched, regulated voltage, wherein the output signal has a fundamental frequency and a gating frequency.
For use in a tire pressure monitoring system, a method of generating an initiator output signal, the method comprising:
- generating the output signal at a fundamental frequency in response to a switched, regulated voltage;
- and
- gating the output signal at a gating frequency.
A reduced power consumption tire pressure monitoring system initiator generator comprising:
- a switching circuit configured to generate a switched, unregulated voltage in response to a supply voltage and an enable signal;
- a regulator configured to generate a switched, regulated voltage in response to the unregulated voltage;
- and
- an oscillator/divider configured to generate an output signal in response to the switched, regulated voltage, wherein the output signal has a fundamental frequency and a gating frequency.
