Title:
【発明の名称】インピーダンス変換フィルタリングを行なう回路装置
Document Type and Number:
Japanese Patent JP2002544695
Kind Code:
A
Abstract:
A circuit arrangement for providing impedance translation filtering comprises a first path and a second path. In a base band variant the first path is a feed forward path which comprises first and second series connected transconductance gain stages (10, 12), and the second path is a feedback which comprises third and fourth transconductance gain stages (18, 20), each having an inverting output. An output of the first gain stage is coupled to an input of the fourth gain stage. In operation, the impedance presented at its output determines the impedance presented at an input of the circuit arrangement.
