Abstract: A phase or frequency locked-loop circuit includes an oscillator configured to generate an output clock signal having a frequency set by an oscillator control signal. A modulator circuit receives a first signal and a second signal and is configured to generate a control signal having a value modulated in response to the first and second signals. A filter circuit generates the oscillator control signal by filtering the control signal. A delta-sigma modulator circuit operates to modulate the second signal in response to a modulation profile. As a result, the output clock signal is a spread spectrum clock signal.

Abstract: A reference voltage generator circuit includes a circuit that generates a complementary to absolute temperature (CTAT) voltage and a proportional to absolute temperature (PTAT) current. An output current circuit generates, from the PTAT current, a sink PTAT current sunk from a first node and a source PTAT current sourced to a second node, wherein the sink and source PTAT currents are equal. A resistor is directly connected between the first node and the second node. A divider circuit divides the CTAT voltage to generate a divided CTAT voltage applied to the first node. A voltage at the second node is a fractional bandgap reference voltage equal to a sum of the divided CTAT voltage and a voltage drop across the resistor that is proportional to a resistor current equal to the sink and source PTAT currents.

Abstract: A method includes receiving a data packet transmitted by a near field communications (NFC) device at a NFC controller. Whether the data packet includes application identifier routing information is determined, and based thereupon the data packet is routed to a default application identifier routing address based on a look-up table lacking an application identifier routing address associated with the application identifier routing information. Whether the data packet includes protocol routing information is determined based upon the data packet lacking the application identifier routing information, and the data packet is routed to a default protocol routing address based upon the look-up table lacking a protocol routing address associated with the protocol routing information, using the NFC controller. The default application identifier routing address is different than the default protocol routing address.

Abstract: An electronic device described herein includes a sensing unit having at least one sensor to acquire sensing data. An associated computing device extracts sensor specific features from the sensing data, and generates a motion activity vector, a voice activity vector, and a spatial environment vector as a function of the sensor specific features. The motion activity vector, voice activity vector, and spatial environment vector are processed to determine a base level context of the electronic device relative to its surroundings, with the base level context having aspects each based on the motion activity vector, voice activity vector, and spatial environment vector. Meta level context of the electronic device relative to its surroundings is determined as a function of the base level context, with the meta level context being at least one inference made from at least two aspects of the plurality of aspects of the base level context.

The device also includes at least one dummy pixel having a dummy OLED diode having a cathode to receive the cathode voltage, and an anode, and a dummy control circuit coupled to the anode of the OLED diode and having a power supply terminal. The dummy OLED diode and the dummy control circuit are substantially similar to the OLED diode and the control circuit. First regulation circuitry is configured to deliver a reference current to the power supply terminal to thereby generate a voltage, and second regulation circuitry is configured to regulate the cathode voltage so as to maintain the voltage at the power supply terminal at a given level.
