Patent number: 8849886Abstract: 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.Type: GrantFiled: July 21, 2011Date of Patent: September 30, 2014Assignee: Apple Inc.Inventors: Benjamin W. Cook, Axel D. Berny

Patent number: 8797146Abstract: An autonomous battery-free microwave frequency communication device which includes a capacitance, at least one antenna, a microwave energy harvesting system, a microwave frequency transceiver, and a control system. The energy harvesting system is configured to harvest and store microwave energy received via the antenna onto the capacitance. The transceiver is empowered by energy stored on the capacitance, and is configured to autonomously generate a microwave frequency carrier and to autonomously transmit information using the microwave frequency carrier according to a predetermined communications protocol via the antenna. The control system is empowered by energy stored on the capacitance, and is configured to provide information for transmission. Energy may be harvested from various communication forms, such as wireless network protocols or cellular communications. The frequency band from which energy is harvested may differ from the frequency band used for communications.Type: GrantFiled: April 22, 2011Date of Patent: August 5, 2014Assignee: Apple Inc.Inventors: Benjamin W.

Patent number: 8543055Abstract: 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 which includes capacitors and switches operatively coupled the capacitors and the one or more input and output nodes. 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. 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. Furthermore, each of at least three capacitors are configured to capture charge from the input signal and to add constructively to deliver charge to at least one other capacitor coupled to the output node.Type: GrantFiled: May 6, 2011Date of Patent: September 24, 2013Assignee: Apple Inc.Inventors: Benjamin W. Cook, Axel D. Berny

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.Type: GrantFiled: May 6, 2011Date of Patent: July 30, 2013Assignee: Passif Semiconductor Corp.Inventors: Benjamin W.

Publication number: 20120087503Abstract: 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.Type: ApplicationFiled: October 6, 2011Publication date: April 12, 2012Applicant: Passif Semiconductor Corp.Inventors: Clarke S.
