论文提出了一种用于WCDMA/EDGE手机的无电感前端接收机，采用65nm CMOS工艺，通过消除电感器显著减小了芯片面积，解决了多频段手机中LNA数量多、面积大的问题。
Bernard Tenbroek1, Jon Strange1, Walid Ali-Ahmad2 1 3 MediaTek, West Malling, United Kingdom, 2MediaTek, Singapore, Singapore, MediaTek, Cambridge, United Kingdom The spectrum allocated for the operation of cellular services is country dependent and fragmented in several frequency bands [1]. Mobile phones, to be usable globally, are therefore required to support many bands. The lack of suitable tuneable pre-selection filters and duplexers mandates the use of a large number of low-noise amplifiers (LNAs) in the receiver section of the transceiver. Minimization of the area occupied by the LNAs is therefore important. Virtually every transceiver for mobile phone applications published to date makes use of LNAs employing on-chip [3,5] or on-passivation [4] spiral inductors. Spiral inductors are large and do not scale with technology, leading to an increasing relative cost of the receiver front-end with newer technology nodes. Post-passivation and SiP technologies also add noticeably to the
