摘要： A PCB includes a plurality of layers spaced apart in a vertical direction, a first detection pattern and a second detection pattern and pads connected to the first detection pattern and the second detection pattern. The first detection pattern and the second detection pattern are provided in a respective one of a first layer and a second layer adjacent to each other such that the first detection pattern and the second detection pattern are opposed to each other. The pads are provided in an outmost layer. Each of the first detection pattern and the second detection includes at least one main segment extending in at least one of first and second horizontal directions and a diagonal direction. A time domain reflectometry connected to a pair of pads detects a misalignment of the PCB by measuring differential characteristic impedance of the first detection pattern and the second detection pattern.

摘要： A direct-current (DC)-DC converter includes a converting circuit including an inductor element. The converting circuit is configured to generate an output voltage from an input voltage based on a switching operation. An inductor current emulator is configured to adjust at least one parameter for changing a current peak value of the inductor element in response to a change in a level of the input voltage and is configured to generate an internal voltage based on the at least one parameter, which is adjusted. The inductor current emulator is configured to generate a control signal for controlling the switching operation such that current of the inductor element has a pattern corresponding to a pattern of the internal voltage.
