Title:
POWER SUPPLY CIRCUIT AND POWER SUPPLY METHOD
Document Type and Number:
Japanese Patent JP2013168914
Kind Code:
A
Abstract:
To provide a technique for achieving a power supply circuit which is capable of supplying a voltage to a device connected to a coil for outputting a differential signal and is excellent in phase characteristics of the differential signal over a wide band.
The power supply circuit includes a first coil to or from which a differential signal is inputted or outputted, a transmission line connected between the midpoint of the first coil and a power source, and a capacitive element connected between the transmission line and a ground potential.
