摘要： Technologies for the sensing of biofeedback signals of a user include a body area network (BAN) system comprising one or more biofeedback sensors and one or more BAN controllers. The biofeedback sensors are configured to sense BAN signals, which may include biofeedback signals and body-coupled communication (BCC) signals. To facilitate communication, the biofeedback sensors may demultiplex the sensed BAN signals into biofeedback signals and incoming BCC signals. Similarly, the biofeedback sensors may multiplex outgoing BCC signals with sensed biofeedback signals. The BAN controller may communicate in a similar manner. Additionally, the BAN controller may process incoming BCC signals and provide feedback to the user based on BCC signals received from the biofeedback sensors.

摘要： Systems, apparatuses and methods may provide for a transmit circuit including a light source and a receive circuit including a photodetector and a transimpedance amplifier (TIA) coupled to the photodetector. Additionally, a calibration circuit may be coupled to the transmit circuit and the receive circuit, wherein the calibration circuit includes a current controller to set an operational current of the light source to a minimum value that results in a target output voltage of the receive circuit. In one example, the gain of the TIA remains substantially constant during calibration of the receive circuit.

摘要： According to various embodiments, a system, an apparatus and a method are presented that relate to determining and correcting signal imbalances between output samples of an analog-to-digital (A-D) converter array (that may be implemented as part of a wideband ADC). A statistic module and correction module are associated with the A-D converter array. The statistic module is configured to receive digital samples from the plurality of A-D converters, and generate a statistical sample value for each A-D converter using a set of digital samples received therefrom. The correction module is configured to, for at least one of the plurality of A-D converters, determine an offset value by comparing the statistical sample value for the at least one of the plurality of A-D converters with a reference value, and apply the offset value to a digital sample from that at least one A-D converter to generate a corrected digital sample.

摘要： Embodiments may comprise logic such as hardware and/or code for high-speed digital-to-analog conversion of signals. Many embodiments comprise a demultiplexer to distribute sets of bits to digital-to-analog converters, the digital-to-analog converters to receive the sets of bits and the operate concurrently to convert the sets of bits from digital representations of signal segments to output analog signal segments, and an interleaver to interleave the analog signal segments from each of digital-to-analog converters in the sequence to generate an analog signal. In many embodiments, the interleaver is adapted to interleave the analog signal segments by latching magnitudes of each of the analog signal segments to an interleaved output near ends of clock cycles to attenuate non-linearities in the magnitudes of each of the analog signal segments when the magnitudes are output.
