Abstract: Provided herein are methods and systems that provide automatic compensation for frequency attenuation of a video signal transmitted over a cable. In accordance with an embodiment, a system includes an equalizer and a compensation controller. The equalizer receives a video signal that was transmitted over a cable, provides compensation for frequency attenuation that occurred during the transmission over the cable, and outputs a compensated video signal. The compensation controller automatically adjusts the compensation provided by the equalizer based on comparisons of one or more portions of the compensated video signal to one or more reference voltage levels.

Abstract: Systems and methods for determining an unknown QPSK or QAM constellation from a set of possible received constellations are described. One method utilizes a histogram of the power of the signal after inter-symbol-interference has been minimized with a modified constant modulus algorithm equalizer. The constellation may be determined before carrier frequency and phase has been fully recovered. An unknown QPSK or QAM constellation may be identified before or after equalization using disclosed methods for analyzing an output power histogram.

Abstract: A high bandwidth, feed-forward oscillator generates a ramp or sawtooth voltage for controlling the operation of a pulse width modulator-based, switched DC power supply circuit. The oscillator is operative to effectively immediately adjust the slope of each rising and falling portion of the ramp/sawtooth signal, as necessary, in proportion to the magnitude of the input voltage, while maintaining the frequency of the ramp waveform effectively constant. A comparator network establishes a difference between peak and valley portions of the sawtooth in accordance with input voltage. In response to a change in input voltage a control circuit modifies the value of the difference between the peak and valley portions to define a new set of respective peak and valley portions VpeakNEW and VvalleyNEW, and immediately causes the sawtooth waveform to transition to the new set of respective peak and valley portions VpeakNEW and VvalleyNEW at said prescribed frequency.

Abstract: An arrangement for measuring current through a phase section of a buck mode DC-DC converter includes an auxiliary integrated circuit containing an auxiliary power MOSFET and a pilot MOSFET coupled in parallel with a current path through a high side MOSFET of a half-bridge of the converter. The pilot MOSFET has a current path coupled to a current measurement terminal. The MOSFETs of the auxiliary circuit are time division multiplexed with the high side MOSFET, whereby a determination of current through the auxiliary high side MOSFET is based upon current through the pilot device and the geometric ratio of the size of the pilot device to that of the high side auxiliary MOSFET. The high side MOSFET is activated for a large number of switching cycles relative to the pilot circuitry, but the pilot circuitry is activated sufficiently often to derive a relatively accurate measure of current flow.
