摘要： An RF modulator includes a C/L delay compensation function of compensating for a delay of a luminance signal with respect to a chrominance signal occurring during demodulating a video signal in a TV set. The RF modulator includes a C/L delay compensation unit delaying a luminance signal by 170 nsec and combining the delayed luminance signal with a chrominance signal to output a composite image signal having a C/l delay of −170 nsec and a frequency modulation unit modulating the video signal received from the C/L delay compensation unit into a high frequency signal of a predetermined broadcasting channel in a single module or package. The RF modulator outputs a video signal having the luminance signal delayed by 170 nsec with respect to the chrominance signal and complies with a C/L delay standard without adding any additional C/L delay compensation unit to the RF modulator.

摘要： A high speed low powered 4-2 compressor according to the present invention performs an XOR/XNOR operation of input data by using a single input type NAND/NOR logic circuit and a dual input type NAND/NOR logic circuit. Thus, delays to generate complementary signals are avoided. In addition, the 4-2 compressor uses a single railed multiplexer instead of a dual railed multiplexer, so that gate drive nodes and internal load capacitance are reduced. As a result, circuit area and power consumption of the 4-2 compressor are reduced.

摘要： A current to voltage conversion circuit for improving the speed of a photoelectric conversion device and frequency characteristics of an amplifier by improving a method for switching the gain of an amplification circuit for a photo detector integrated circuit (PDIC). Photocurrent generated in the photoelectric conversion device, such as a photodiode, is transferred to the amplifier by means of current mirroring, so as to raise a bias voltage to the photoelectric conversion device and enhance a response speed thereof. Further, the amount of current generated in the photoelectric conversion device is adjusted through control of a resistance ratio of a current mirror circuit. Therefore, a fixed feedback resistor can be used for the amplifier irrespective of modes, so as to enhance frequency characteristics of the amplifier.

摘要： A digital-to-analog converter (DAC) for a display device is provided. The DAC includes an amplifier and a current decoder. The amplifier receives a gradation voltage with respect to upper bits in data of k bits through a non-inverting input terminal, and varies the input gradation voltage according to a voltage applied to an inverting input terminal. The current decoder allows a predetermined constant current to flow therethrough according to input data of lower bits, which do not include the upper bits, to thereby vary the voltage applied to the inverting input terminal. The current decoder further adjusts the gradation voltage outputted by the amplifier according to the varied voltage.
