Abstract: An example playback device includes a first interface for receiving a first audio signal from a first audio source; a second interface for receiving a second audio signal from a second audio source; and a processor configured to: cause the playback device to playback the second audio signal; determine that the first audio signal is present at the first interface; in response to determining that the first audio signal is present at the first interface, (i) cease playback of the second audio signal being played by the playback device and (ii) cause the playback device to playback the first audio signal; receive an instruction to stop the playback device from playing the first audio signal while the first audio signal is still present at the first interface; and arm the playback device such that a subsequent presence of the first audio signal at the first interface causes the playback device to play the first audio signal.

Abstract: Methods and systems are provided for volume interactions for connected playback devices. In an example implementation, a first playback device applies a state variable update associated with a group of playback devices comprising the first playback device and one or more second playback devices. The state variable update indicates a limited volume range associated with the first playback device. The first playback device renders audio content in synchrony with the one or more second playback devices. Rendering the audio content involves a subwoofer speaker of the first playback device rendering a bass frequency component of the audio content. The first playback device receives input data indicating a group volume adjustment for the group of playback devices and adjusting a playback volume of the first playback device based on the group volume adjustment and the limited volume range.

Abstract: A digitally controlled amplifier (DCA) has a drive (e.g., bipolar junction) transistor with a base to accept an input signal and a collector to supply an output signal. The DCA also includes n switchable gain amplifier networks (SGANs). Each SGAN has a signal input connected to the collector of the drive transistor, an input to accept a logic signal, and a signal output to supply a switchable gain AC output signal to a load in response to the logic signal. The SGAN signal outputs are connected together, typically in parallel, to supply a digitally controlled AC output gain. An auxiliary SGAN may be connected to supply a constant gain AC output signal. Each of the SGANs may have an identical switchable AC gain and accept an independent logic signal to supply (n+1) levels of digitally controlled AC output gain.

Abstract: An amplifier circuit can include an amplifier and a resistor network coupled to the amplifier. The resistor network can include a range resistor coupled in parallel to a resistor string, and one or more switches coupled to the resistor string. The resistor network can be used to calibrate gain and common mode rejection ratio (CMRR) of the amplifier circuit.

Abstract: A receiver front end capable of receiving and processing intraband non-contiguous carrier aggregate (CA) signals using multiple low noise amplifiers (LNAs) is disclosed herein. A cascode having a “common source” input stage and a “common gate” output stage can be turned on or off using the gate of the output stage. A first switch is provided that allows a connection to be either established or broken between the source terminal of the input stage of each cascode. Further switches used for switching degeneration inductors, gate/sources caps and gate to ground caps for each legs can be used to further improve the matching performance of the invention.
