Abstract: A feedback control circuit of a pulse-frequency modulation (PFM) converter includes a multiplexer circuit and a detection circuit. The multiplexer circuit is arranged to receive a plurality of candidate peak current values, and output one of the plurality of candidate peak current values as a target peak current value according to a selection control signal, wherein a peak current value of an inductor current pulse of the PFM converter is subject to the target peak current value. The detection circuit is arranged to adaptively adjust the selection control signal according to a pulse interval between two successive inductor current pulses of the PFM converter.

Abstract: An adaptive active noise control (ANC) system includes an ANC circuit and a control circuit. The ANC circuit generates an anti-noise signal, and includes at least one adaptive filter. The control circuit receives a first input signal derived from a reference signal output by a reference microphone that picks up ambient noise, receives a second input signal derived from an error signal output by an error microphone that picks up remnant noise resulting from noise reduction, and performs a comparison operation based on a first characteristic value of the first input signal and a second characteristic value of the second input signal to control the at least one adaptive filter.

Abstract: An acoustic-wave device with active calibration mechanism is provided. The acoustic-wave device with active calibration mechanism includes at least one acoustic-wave duplexer, a voltage-controlled oscillator (VCO), a frequency discriminator and a control circuit. The acoustic-wave duplexer includes a TX filter and an RX filter. The voltage-controlled oscillator includes a calibration resonator and a tunable negative impedance circuit. The TX filter, the RX filter and the calibration resonator are disposed on the same piezoelectric substrate. The frequency discriminator generates a calibration signal according to a frequency deviation of the calibration resonator. The control circuit is connected to the acoustic-wave duplexer and the frequency discriminator. The control circuit adjusts an operating frequency of the TX filter or an operating frequency of the RX filter according to the calibration signal.

Abstract: A Bluetooth audio packet sharing method comprises an electronic device, a first Bluetooth speaker and at least one second Bluetooth speaker. The electronic device establishes Bluetooth connection with the first Bluetooth speaker by a Bluetooth link information, and the first Bluetooth speaker is able to receive an audio packet from the electronic device. The electronic device or the first Bluetooth speaker broadcasts the Bluetooth link information. The second Bluetooth speaker is close to the electronic device and the first Bluetooth speaker, and receives the link information broadcasted by the first Bluetooth device. Thus, the second Bluetooth speaker is able to receive or share the audio packet transmitted by the electronic device by the Bluetooth link information.
