Title:
VARIABLE INDUCTOR CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/171539
Kind Code:
A1
Abstract:
One inductor (1a) and another inductor (1b) are magnetically coupled to each other. A variable current source (2) controls a current flowing through the one inductor (1a). By controlling the current flowing through the one inductor (1a), the inductance value of the other inductor (1b) is made variable.
