  • High frequency amplification circuit and mobile communication terminal using the same
    Publication number: 20060040629
    Abstract: A gain control circuit 12 comprises an FET 41 operating as a variable resistor. A gate terminal of the FET 41 is supplied with a control voltage VC applied to a gain control terminal 23. A source terminal and a drain terminal of the FET 41 are supplied with a reference voltage Vref1 obtained by a reference voltage circuit 13. The reference voltage Vref1 is controlled so as to compensate for a variation in the threshold voltage of the FET 41. The resistance value of the FET 41 is changed in accordance with the control voltage VC, and thus the gain of the high frequency amplification circuit 10 is also continuously changed.

  • Method of reviewing detected defects
    Publication number: 20060038986
    Abstract: A method to solve the problem of a technique generally used to detect a defect of a semiconductor by calculating the differential image based on pattern matching, which requires that a reference image must be picked up to pick up an image of the inspection position in an area with the semiconductor pattern having no periodicity, resulting in a low throughput. The image of the inspection position is divided into local areas, each local area is matched with the local area of the image already stored and the difference between the local areas thus matched is determined to extract a defect area.
