摘要： A real-time sample rate converter having a non-polynomial convolution kernel provides reduction in die area and power for performing sample rate conversion in real-time. A non-polynomial convolution kernel, which may be a gaussian operator, is used to determine output sample values from values of an incoming stream of values. If the input sample rate is higher than the output sample rate, the input sample stream is convolved with the gaussian kernel and then decimated to yield the output stream. If the input sample rate is lower than the output sample rate, the input stream is resampled to a small multiple of the output sample rate and convolved with the gaussian kernel to produce the output sample stream directly.

摘要： A dynamic logic circuit apparatus and method for reducing leakage power consumption via separate clock and output stage control reduces power consumption of processors and other systems incorporating dynamic circuits. The power control signal may be a delayed version of the logic clock and turns on the output inverter foot device after the dynamic node has had sufficient time to evaluate, providing a fast evaluate time and reducing leakage through the inverter input when the foot device is off. Alternatively, a coarsely timed static power control signal may be used to control the inverter foot devices. The drains of the inverter foot devices can be commonly connected across multiple circuits, reducing the foot device total area.

摘要： An integrated circuit (IC) provides on-line, wafer-level, die-level, or package-level thermal calibration of an integrated thin-film resistor, by thermally enclosing the thin-film resistor with metal layers formed above and below the thin-film resistor along its length and width. Metal vias thermally couple the metal layers to the substrate to at least partially equalize the temperature of the metal layers and the thin-film resistor and the substrate. A controllable heat source, which may be provided by another thin-film resistor integrated on or below the substrate, and a reference temperature sensor provide heating/calibration measurement of the resistance of the thin-film resistor over a range of temperature. The reference temperature sensor may be provided within the IC, for example, integrated on the substrate or packaged with the die containing the thin-film resistor, or may be otherwise thermally coupled to the metal layers, e.g., by an extension of one of the metal layers.

摘要： A class-D amplifier includes a first differential modulator circuit, a first driver circuit including a first high-side switch and a first low-side switch. An input of the first driver circuit may be coupled to a first output of the first differential modulator circuit so that the first differential modulator circuit controls the first driver circuit. The class-D amplifier may also include a second driver circuit including a second high-side switch and a second low-side switch coupling the second and control logic that selects between a single-ended operating state and a differential operating state of the class-D amplifier circuit. The control logic may selectively determine the input of the second driver circuit in conformity with a current operating state of the class-D amplifier circuit so that the first differential modulator circuit controls the second driver circuit when the differential operating state is selected.

摘要： Methods, systems, circuits and computer program products provide an output signal to drive an electromechanical transducer that selectively contains a cooling component when a thermal limit of a voice coil of the electromechanical transducer is exceeded and which air-cools the transducer by convection. An indication of a temperature of a voice coil of the electromechanical transducer is determined and compared with a thermal limit of the transducer. If the thermal limit of the transducer is exceeded by the indication of the temperature of the voice coil, the cooling component is introduced to the output signal that drives the transducer. The cooling component is a signal having a frequency within a low-frequency resonance portion of the response of the electromechanical transducer, so that additional air convection is caused at the transducer to remove heat from the voice coil due to the cooling component of the output signal.

摘要： An audio output system for providing an output signal to a micro-speaker provides energy reduction and thermal protection by removing components of an input signal from which the output signal is generated, so that the audio power output system does not expend power reproducing portions of the audio information that would not be perceived by a listener. The micro-speaker has a resonant frequency such that substantial content of the audio information lies below the resonant frequency. A processing subsystem receives the audio information and generates the output signal by filtering the audio information with a response simulating the micro-speaker and an acoustic path to the listener, and comparing the filtered audio information with a frequency-dependent threshold of hearing. The processing subsystem then removes portions of the audio information that have an amplitude below the frequency-dependent threshold of hearing.

摘要： A power output circuit supplies an audio power output signal that is adjusted to prevent clipping when needed based on an estimate of available energy from the power supply supplying the power output circuit. The power output circuit may be an audio power output circuit that generates an audio power output signal from samples of an audio program that are stored in a buffer. A processing block determines an energy requirement for producing the audio power output signal from the audio program and adjusts an amplitude of the audio power output signal in conformity with the determined energy requirement and an available energy determined for the power supply so that the audio power output signal is reproduced without clipping of the audio power output signal.
