  • Publication number: 20100141636
    Abstract: Row propagation delay is the duration it takes for a signal to travel the length of a row in a flat panel display matrix. Row propagation delay compensation modifies when column voltages are applied to each column in a flat panel matrix by substantially matching the delay for its position relative to the length of the row. A ternary signal generated by the timing controller with embedded clock and data information is buffered at the timing controller and transmitted to each column driver as required to substantially match row propagation delay while minimizing system interconnects and column driver circuitry.

  • Publication number: 20100039306
    Abstract: A method of analog-to-digital conversion over n bits of an analog signal, including the steps of: comparing the amplitude of the analog signal with a threshold representing the amplitude of the full-scale analog signal divided by 2k, where k is an integer smaller than n; performing an analog-to-digital conversion of the analog signal over n-k bits to obtain the n-k most significant bits of a binary word over n bits if the result of the comparison step indicates that the amplitude of the input signal is greater than the threshold, and the n-k least significant bits of this binary word otherwise. An analog-to-digital converter and its application to image sensors.

  • Patent number: 7615977
    Abstract: A linear voltage regulator includes a voltage-regulating circuit that controls a power transistor connected to a load. A current-limiting loop circuit includes a common input/output node that is coupled to a control electrode of the power transistor. The loop senses whether a current representative of the current flowing through the power transistor is above a reference current, and in response thereto delivers a non-zero output current to the control electrode of the power transistor. Otherwise, the loop does not deliver any output current to the control electrode of the power transistor.

  • Patent number: 7611279
    Abstract: An embodiment of a temperature sensor providing a digital signal representative of temperature comprises a measurement unit providing a first measurement current equal to the sum of at least a first current proportional to temperature and of a second current; a comparator capable of providing a comparison signal which depends on the comparison between the first current and the difference between a third current and the second current; a coding unit receiving the comparison signal and providing said digital signal; a digital-to-analog converter capable of providing the second current and the third current, said difference corresponding to the conversion of said digital signal; and a unit for providing a reference voltage.
