    Abstract: The invention relates to a driver circuit used to transmit a digital signal from a source device to a destination device. The driver circuit provides a controlled switching time to improve digital signal quality, while reducing electromagnetic interference. In the circuit, a pair of first switches of a first plurality are coupled in parallel between a first current node and respective ones of first and second output terminals. A plurality of pairs of second switches of a second plurality are coupled in parallel between a respective second current node and the first and second output terminals. Timing circuitry applies input signals to the pair of first switches and successive input signals to the pairs of second switches so as to develop a staggered voltage across a load coupled between the first and second output terminals.

    Abstract: Systems and methods are for implementing a NSV2SV converter that converts a non-scalable video signal to a scalable video signal. In an implementation, a non-scalable video signal encoded in H.264/AVC standard is decoded and segmented into spatial data and motion data. The spatial data is resized into a desired resolution by down-sampling the spatial data. The motion data is also resized in every layer, except in the top layer, of a scalable video coding (SVC) encoder by using an appropriate measure. Further, the motion data is refined based on the resized spatial data in every layer of the SVC encoder. The refined motion data and the down-sampled spatial data are then transformed and entropy encoded in the SVC standard in every layer. The SVC encoded output from every layer is multiplexed to produce a scalable video signal.

    Abstract: A system switches between application of a first supply voltage and a second supply voltage to a load. The second supply voltage is a regulated voltage that is generated from the first supply voltage, or is alternatively generated from a reference voltage, such as bandgap. When the load is supplied from the first supply voltage, the regulated voltage is also generated from the first supply voltage. At or after switching the load to the second supply voltage, the regulated voltage is generated instead from the reference voltage. The load is a clock circuit, such as an oscillator. The controlled switching of the supply voltage for the load in the manner described addresses concerns over introducing errors in the output clock signal when the clock circuit's supply voltage is changed.

    Abstract: Described herein are various principles for operating a transmitter circuit to reduce noise affecting a signal being generated and reducing jitter. In some embodiments, a circuit is operated in a way that switching occurs at or above a bit rate of transmission, such that at least one switch changes state at least for every bit. Operating the circuit in such a way leads to a switching rate that is above a resonant frequency of the circuit and prevents large oscillations and noise from being inserted into the signal and causing communication problems.
