Abstract
A method and apparatus for extending the sleep time for a Bluetooth transceiver circuit uses a fine count signal and a base count signal during the sleep mode, followed by an interval that accounts for wake-up overhead and preparation for the next active mode. The wake-up to active mode is aligned with the timing signal that defines the communication slots in the Bluetooth communications. The extension of the sleep mode until a beginning of a communication slot in active mode is accomplished for wake-up processes that are initiated by an external trigger event as well as for wake-up processes that are initiated as a result of an internal timer. Power consumption is reduced because the circuit does not wake up to active mode before communication can be carried out in a communication slot.
