Abstract: A system including a component of a transceiver, a comparator, a counter, and a calibration circuit. The component receives an input signal comprising packets and based on the input signal, generates output signals to transmit the packets. The comparator compares the output signals to generate a comparison signal. The counter counts cycles of a clock signal to provide a count value. The control device, based on the comparison signal, transitions the counter between incrementing the count value and decrementing the count value. The calibration circuit operates in first and second calibration modes; during the first calibration mode, calibrates the component until the counter transitions a predetermined number of times between incrementing the count value and decrementing the count value; and during the second calibration mode, calibrates the component until (i) the counter transitions between incrementing and decrementing the count value, or (ii) counts a predetermined number of cycles.

Abstract: Different scan modes are provided for Bluetooth devices. In at least some embodiments, a narrowband scanning mode looks for signal energy on individual transmission frequencies at a time. By looking for signal energy rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A midband scanning mode looks for signal energy across multiple different frequencies at a time. Again, by looking for signal energy across multiple different frequencies rather than decoding transmitted packets, at least some of the components in a Bluetooth device can remain in an idle or rest state. A wideband scanning mode looks for signal energies across all relevant frequencies at a time. At least some embodiments enable a Bluetooth device to switch between scanning modes.
