Abstract

This paper presents a reconfigurable multimode matching network employing a multi-tap transformer designed in 130 nm CMOS. By combining a multi-tap transformer and a bank of switched capacitors, it is shown that frequency matching in 2.4 GHz, 5 GHz, or 5-10 GHz bands, is achievable and thus supports multiple standards such as Bluetooth, 802.11a/b/g/n, WiMAX, and UWB.
