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.
