Active and Passive Integrated Filters for Multi-GHz 6G Baseband Applications

Gannedahl, Rikard LU and Sjöland, Henrik LU orcid (2023) 31st Asia-Pacific Microwave Conference, APMC 2023 p.524-526
Abstract

This paper presents the design and comparison of an active Gm-C and a passive baseband filter for 6G applications. Both presented circuits are 5th-order differential low-pass filters with 3-dB cut-off frequencies of 4.9 and 4.7 GHz, respectively, implemented in a 22 nm FD-SOI CMOS technology. The active filter uses back-gate tuning to optimize the transfer function, and achieves a measured in-band IIP3 between -1.0 and -9.1 dBVp, out-of-band IIP3 between 1.0 and 15 dBVp, and input-referred noise of 6.55 nV / √Hz, while consuming 19.9 mW from a 0.8 V supply and occupying 0.05 mm2 core chip area. By utilizing mutual inductance, the footprint of the passive filter is minimized,... (More)
