Title:
VCO結合を低減する方法およびインダクタのレイアウト
Document Type and Number:
Japanese Patent JP2007526642
Kind Code:
A
Abstract:
A radio-frequency transceiver is disclosed. It comprises a first inductor (200, 1000, 1300) with terminals (204a, 204b; 1310a, 1310b). The first inductor (200, 1300) is substantially symmetric about a symmetry axis. The first inductor (200, 1300) has a first loop (206a) and a second loop (206b) arranged such that current in the first loop (206a; 1004; 1002) travels in a direction that is opposite to current in the second loop (206b; 1008) such that electromagnetic field components emanating from the first loop (206a; 1004) and the second loop (206b; 1008) also have opposite directions and tend to counteract each other. The terminals (204a, 204b; 1310a, 1310b) are connected to the second loop (206b).
