    摘要： Disclosed herein are a transmission line of coaxial type and a manufacturing method thereof, capable of preventing a radiative signal loss of signal lines during transmission of an RF signal and removing signal interference between adjacent signal lines, thus allowing signal lines to be compactly arrayed during a manufacture of IC, and reducing a dimension of the IC. The transmission line of coaxial type includes grooves provided on a semiconductor substrate, a first ground layer, an electrically conductive epoxy coated on a flat part of the first ground layer except the grooves, second ground layers provided on the electrically conductive epoxy, a dielectric film provided at a position above the grooves and the second ground layers, a third ground layer provided on an upper surface of the dielectric film, and signal lines placed in spaces defined by the grooves and a lower surface of the dielectric film. In this case, the electrically conductive epoxy is coated on only contact surfaces of the first and second ground layers, and the signal lines are attached to the lower surface of the dielectric film.

    摘要： A digital to analog converter includes first and second capacitors, an operational amplifier and a switching circuit. The operational amplifier includes first and second input terminals and an output terminal, the second input terminal receiving a reference voltage. The switching circuit includes multiple switches which switch in response to corresponding switching signals. The switching circuit connects the second capacitor between the output terminal and the first input terminal of the operational amplifier, while respectively sending first and second voltages to first and second terminals of the first capacitor during a first period. The switching circuit also connects the first capacitor between the output terminal and the first input terminal of the operational amplifier, while respectively sending third and fourth voltages to first and second terminals of the second capacitor during a second period consecutively following the first period.
