Description

technical field [0001] The present invention relates to a semiconductor device, a receiving device, and a transmitting device. Background technique [0002] A semiconductor device generally mounts a semiconductor chip having a signal processing circuit composed of many elements such as transistors and a plurality of bonding pads in a package having a plurality of terminals for inputting or outputting signals to and from the outside. The thin-diameter bonding wires connect the pads of the semiconductor chip and the terminals of the package to each other. [0003] Bonding wires have parasitic inductance. For example, as a typical example of a bonding wire, when the wire length is 1 mm and the wire diameter is 0.015 mm, the parasitic inductance of the bonding wire is about 0.92 nH. When the frequency of the signal is assumed to be 10 GHz, the absolute value of the impedance of the bonding wire is 57.8Ω (=2π×10GHz×0.92nH). In addition, the characteristic impedance of the sign...
