Abstract: A current generator generates a non-linear output current whose temperature coefficient exhibits a prescribed non-linear-to-quasi-linear curvature when a control voltage range is restricted. This particular current characteristic enables a voltage reference employing the current generator for high-order curvature correction to produce an output voltage whose variation is extremely flat over its industry standard operational temperature range.

Abstract: A mode-dependent, battery-coupling switch for a subscriber line interface circuit (SLIC) selectively adjusts its current requirements to provide optimal current handling capability irrespective of the mode of operation of the SLIC. Where current demands of the SLIC are relatively minimal (e.g., on-hook idle mode), the bias is set at a relatively small, default value. During high current demand, such as ringing and off-hook signaling, the bias is set at a relatively large value, to maintain a low voltage drop across the battery-coupling switch.

Abstract: An electrostatic discharge protection circuit for an integrated circuit that reduces unwanted transient currents during normal operations. In one embodiment, the electrostatic discharge protection circuit includes one or more electrostatic bus lines, a plurality of signal bonding pads and charge pumps. The one or more electrostatic bus lines are used to direct electrostatic discharge around internal circuitry. The plurality of signal bonding pads are used to receive external voltage signals. Each signal bonding pad is coupled to an associated electrostatic bus line via an unidirectional conducting device. A charge pump is used on each electrostatic bus line to precharge its associated electrostatic bus line to an associated predetermined voltage level. The precharging of each electrostatic bus line to its predetermined voltage level reduces transient currents through the unidirectional conducting devices when external voltage signals having voltage levels beyond normal supply voltage ranges are applied to the signal bonding pads.

Abstract: To mitigate against base current errors in a current mirror circuit that has limited overhead voltage, a compensated current mirror circuit includes a complementary polarity base current error reduction and auxiliary turn-on circuit, that provides an overhead voltage that enjoys a base-emitter diode drop improvement over the overhead voltage of a conventional circuit. Due to the base current error-reduction transistor in the circuit path from the power supply rail to the input port, the overhead voltage is improved by a base-emitter diode drop larger than the overhead voltage of the conventional circuit. In addition, it further reduces base current error.

Abstract: An output current limiter circuit is effectively insensitive to variations in temperature. A first arm of each of an NPN and a PNP network has a first auxiliary resistor, the current through which is proportional to temperature, and compensates for the negative temperature coefficient of the base-emitter voltage of that arm's (NPN or PNP) transistor, as well as tracks the positive temperature variation in the Vbe-bias control resistor in the other arm of the network. The other arm includes a second additional resistor, the voltage across which is established by a (fixed) bandgap voltage device, that uses a current from which the current through the first arm of the network is derived.

Abstract: Systems and methods for operating cameras are described. An image signal received from an image sensor can be processed as a plurality of video signals representative of the image signal. An encoder may combine baseband and digital video signals in an output signal for transmission over a cable. The video signals may include substantially isochronous baseband and digital video signals. The baseband video signal can comprise a standard definition analog video signal and the digital video signal may be frequency modulated before combining with the baseband video signal and/or transmitting wirelessly. The digital video signal may be a compressed high definition digital video signal. A decoder demodulates an upstream signal to obtain a control signal for controlling the position and orientation of the camera and content of the baseband and digital video signals.

Abstract: Signals propagating from an aggressor communication channel can cause detrimental interference in a victim communication channel. One or more noise cancellers can generate an interference compensation signal to suppress or cancel the interference based on one or more settings. A controller can execute algorithms to find preferred settings for the noise canceller(s). The controller can use a feedback signal (e.g., receive signal quality indicator) received from a victim receiver during the execution of the algorithm(s) to find the preferred settings. One exemplary algorithm includes sequentially evaluating the feedback resulting from a predetermined list of settings. Another algorithm includes determining whether to move from one setting to the next based on the feedback values for both settings. Yet another algorithm includes evaluating a number of sample settings to determine which of the sample settings result in a better feedback value and searching around that sample setting for a preferred setting.
