Abstract
This paper presents the overall architecture, first test structure implementations, and measurement results of an integrated GNSS front-end based on intentional path overlay. The front-end ASIC supports simultaneous multiband, multi-system GNSS reception of GPS L5 / Galileo E5 / GLONASS G3 and GPS L1 / Galileo E1 / GLONASS G1 signals with up to 52MHz bandwidth while using only one common baseband path thanks to an intentional analog signal overlay. Test structures of the RF and baseband parts were realized in a 1.8 V, 150nm RF-CMOS technology packaged in a QFN48 housings with full ESD protection. Both chips are described in detail regarding their design and their actual measurement results.
