Space efficient integrated circuit with passive devices
Abstract:
A multimodal integrated circuit (IC) is provided, comprising, first (74) and second (76) semiconductor (SC) devices, and first (78) and second (80) integrated passive devices (IPDs) coupled, respectively, to the first (74) and second (76) SC devices, wherein the first IPD (78) overlies the second SC device (76) and the second IPD (80) overlies the first SC device (74) chosen such that the underlying SC device (74, 76) is not active at the same time as its overlying IPD (80, 78). By placing the IPDs (78, 80) over the SC devices (76, 74) a compact IC layout is obtained. Since the overlying IPD (78, 80) and underlying SC (76, 74) are not active at the same time, undesirable cross-talk (68, 69) between the IPDs (78, 80) and the SC devices (76, 74) is avoided. This arrangement applies to any IC having multiple signal paths (RF1, RF2) where the IPDs (78, 80) of a first path (RF1, RF2) may be placed over the SC devices (76, 74) of a second path (RF2, RF1) not active at the same time. This is especially useful with high frequencies ICs.
Abstract(Chinese):

提供了一种多模式集成电路（IC），其包括第一（74）和第二（76）半导体（SC）器件以及第一（78）和第二（80）集成无源器件（IPD），分别耦合到第一 （74）和第二（76）个SC设备，其中所述第一IPD（78）覆盖所述第二SC设备（76），并且所述第二IPD（80）覆盖所选择的所述第一SC设备（74），使得所述下面的SC设备 ，76）在上层IPD的同时不起作用（80,78）。 通过将IPD（78,80）放置在SC设备（76,74）上，可以获得紧凑的IC布局。 由于上覆IPD（78,80）和底层SC（76,74）同时不起作用，IPD（78,80）与SC设备（76,74）之间的不期望的串扰（68,69） ）。 这种布置适用于具有多个信号路径（RF1，RF2）的任何IC，其中第一路径（RF1，RF2）的IPD（78,80）可以放置在第二路径（RF2，RF2）的SC设备（76,74）上 ，RF1）不同时激活。 这对于高频IC尤其有用。
