摘要： The range finder includes a transmitting unit (71) which emits a transmitted wave (75) spread using a spread code at a constant chip rate, a receiving unit (72) which receives a reflected wave (76), a correlation unit (73) which calculates a correlation waveform indicating delay time and a correlation between the transmitted wave (75) and the reflected wave (76), and a distance calculation unit (74) which calculates, from a peak position in the waveform, a distance to the object. The correlation unit (73) calculates the correlation waveform obtained when changing the delay time for each range gate. The distance calculation unit (74) calculates the distance to the object by calculating, at a resolution finer than the range gate, a delay time corresponding to the peak in the correlation wave using a highest-correlation point and an adjacent higher-correlation point in the wave form.

摘要： A semiconductor integrated circuit device with a balun which is formed above a conductive semiconductor substrate and which includes a dielectric film, an unbalanced line for transmitting an unbalanced signal, and balanced lines for transmitting a balanced signal. The unbalanced line is placed opposite to the balanced lines via a nano-composite film that is a region of the dielectric film. The nano-composite film, interposed between the unbalanced line and the balanced lines, has a relative permittivity higher than that of other regions of the dielectric film. This allows suppression of electromagnetic coupling of transmission lines or passive elements other than the balun, thereby providing a semiconductor device with a wide-band and small-size balun.
