Abstract: A biasing device for direct current (DC) biasing a linear power amplifier that comprises multiple linear power amplifier circuits that are ideally identical to each other; wherein the biasing device may include a replica circuit that is a replica of a linear power amplifier circuit of the multiple linear power amplifier circuits; and a bias control circuit; wherein the bias control circuit is configured to feed the replica circuit with one or more DC biasing signals thereby maintaining at a constant value a replica DC current that is consumed by the replica circuit, and maintaining at a fixed value a replica DC voltage of a replica output node of the replica circuit; and wherein the replica circuit is coupled the multiple linear power amplifier circuits and is configured to supply DC voltage bias signals that force each linear power amplifier circuit of the multiple linear power amplifier circuits to consume a linear power amplifier circuit DC current that equals the replica DC current, when the linear power amplifier circuit is fed with a linear power amplifier DC voltage that either equals the replica DC voltage or differs from the replica DC voltage by a fraction of the replica DC voltage.

Abstract: Methods and systems are provided for enhancing listening intelligibility in electronic devices. A vibration sensor may be used to generate feedback corresponding to vibrations caused by the outputting of the acoustic signals, and the feedback may be used in adjusting the listening intelligibility stage. In some instances, a microphone may be used to obtain audio input corresponding to ambient noise affecting intelligibility of audio outputted, as acoustic signals, via a speaker, to a user. The audio input may be used to control a listening intelligibility stage applied to audio content when the acoustic signals are generated for outputting by the speaker. In particular, the listening intelligibility stage may comprise application of dynamic time-scale modifications.

Abstract: A novel and useful linear, efficient, smart wideband CMOS hybrid power amplifier that combined an analog linear amplification path and a digital power amplification (DPA) path. PA path control logic analyzes the input I and Q signals and determines which amplification paths to steer the input I and Q signals to. The analog linear amplification path comprises digital to analog converters for both I and Q paths and one or more analog linear power amplifiers. The digital power amplification path comprises I and Q up-sampling circuits and I and Q RF DAC circuits (e.g., digital PA circuits). In operation, the PA path control logic compares the I and Q signals to thresholds (which may or may not be different) and based on the comparisons, selects one or more paths for the input I and Q signals. Whether the signals from the analog and digital amplification paths are to be combined or selected (i.e. switched), the PA path control circuit is operative to generate select (switch) control signals which are applied to summer/selector elements which generate the output of the hybrid PA.

Abstract: A two-port air pump speaker that includes at least two active, phase-modulated, bi-directional shutters and an ultrasonic pumping chamber having at least two ports; a first port facing towards the listener, the forward port, and a second port facing another direction, the backward port which may be behind an acoustic baffle or inside a speaker enclosure. A two-port speaker with two active steering shutters can create continuous bi-directional airflow which leads to low distortion reproduction of low audio frequencies. The same improved design can be used also for other applications where acoustic modulation is required, especially in ultrasonic frequencies.

Abstract: A MEMS speaker that includes a control unit and multiple MEMS elements that include a membrane positioned in a first plane, a blind that is positioned in a second plane and a shutter that is positioned in a third plane. The control unit is configured to control the multiple MEMS elements to operate in an audio output mode or an ultrasonic output mode. The MEMS speaker is configured, when operating in the ultrasonic output mode, to oscillate at least one of the membrane, blind and shutter thereby generating an ultrasonic signal without audio-modulating the ultrasonic signal. The MEMS speaker is configured, when operating in the audio output mode, to oscillate the membrane thereby generating the ultrasonic signal and oscillate at least one of the shutter and the blind thereby modulating the ultrasonic acoustic signal to generate an audio signal.
