Abstract: A discrete-time analog filter including multiple storage cells each coupled to common input and output ports and each including at least one of capacitor and at least one switch. Each cell periodically samples an input signal and contributes to an output signal. At least two cells sample the input signal at different frequencies. The cells may be grouped together into one or more filter taps, where each filter tap may have a specified timing delay. Timing signals of a given tap may be non-overlapping phases of a given frequency. Cells may have a fixed or programmable capacitance associated with a corresponding weighting coefficient, and different taps may have different weighting coefficients. Taps may be coupled to implement a negative weighting coefficient. Programmable gain may be implemented with switches or by tap output coupling including sub-filter summing arrangements. Self-timed cells based on a master clock are disclosed.

Abstract: A passive frequency translator with positive conversion voltage gain including at least one input node for receiving an input signal, at least one output node for providing an output signal, and a network coupled to the at least one input node and to the at least one output node, in which the network includes multiple capacitors and switches operatively coupled thereto. The switches are controlled by corresponding clock signals to capture charge of the input signal onto the capacitors and to develop the output signal by performing frequency translation of the input signal by a mixing frequency in such a manner that DC energy of the input signal is substantially blocked from the output signal. The output signal has a net voltage gain relative to the input signal in which energy of the output signal is predominantly derived from energy of the input signal.

Abstract: An amplitude control system including one or more multi-element array power amplifiers (MEA-PA), each MEA-PA including multiple amplifiers, multiple capacitors, and multiple enable circuits. Each amplifier has an input coupled to a common input node and an output coupled to a corresponding one of multiple intermediate nodes. Each capacitor has a first end coupled to an output node and a second end coupled to a corresponding intermediate node. The enable circuits are collectively controlled by an amplitude control value, and each is operative to enable or disable a corresponding amplifier. The enable circuits may be dynamically controlled to modulate amplitude. A coupling circuit may be provided to couple an intermediate node to a reference node when a corresponding amplifier is disabled to adjust a coupling ratio. Each amplifier, when enabled, may receive one of multiple supply reference voltages. The capacitors may have equal capacitance or may be binary-weighted.

Abstract: A wireless multi-channel audio system including an audio source with a wireless transceiver configured to communicate according to a standard wireless protocol and an audio controller, which are collectively configured to establish wireless communications with multiple audio sinks via a corresponding wireless link, to assign each audio sink a corresponding audio channel, to synchronize timing with each audio sink, and to transmit audio information for each audio channel to a corresponding audio sink via a corresponding wireless link. The audio source may inquire as to supported audio parameters, such as sample rate and audio codec, and selects a commonly supported configuration. The audio source may separate audio information into queues for each audio channel for each audio sink. The audio source transmits frames with timestamps and a common start time for synchronization, and the audio sinks use this information to synchronize timing and remain virtually synchronized with each other.
