ELECTRONIC CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electronic circuit device having a power supply structure that can cope with high-speed signals exceeding the GHz band. SOLUTION: A driver transistor 10 is formed on the surface of a semiconductor substrate 1. A power supply ground-pair transmission line 20 which supplies electric power to the driver transistor 10, and a signal ground-pair transmission line 30 which transmits signals to a receiver, are also formed on the semiconductor substrate. The power supply ground-pair transmission line 20 is connected to the drain layer 3 of the driver transistor 10 and a P+-type layer 7 in a P-type well 2. In addition, the signal ground-pair transmission line 30 is connected to the source layer 4 of the transistor 10 and a P+-type layer 8 in the P-type well 2. COPYRIGHT: (C)2004,JPO&NCIPI
