ELECTRONIC CIRCUIT APPARATUS

PROBLEM TO BE SOLVED: To provide an electronic circuit apparatus having a power supplying structure which can handle a high-speed signal over GHz band. SOLUTION: An electronic circuit apparatus comprises a source power supply ground pair transmission line 50 having a power supply line and a ground line arranged while facing each other, three branched power supply ground pair transmission lines 51, 52, and 53 branched from the source power supply ground pair transmission line 50, respectively composed of a power supply line and a ground pair line arranged while facing each other, three driver transistors 55, 56, and 57 connected to these branched power supply ground pair transmission lines 51, 52, and 53, respectively, three signal ground pair transmission lines 58, 59, and 60 each of which is driven by output signals from the driver transistors 55, 56, and 57 and composed of a signal line and a ground line arranged while facing each other, and a receiver circuit which receives signals transmitted from these signal ground pair transmission lines.
