Capacitive Cancellation in Compact Integrated Multi-GHz Differential Passive Baseband Filters

Gannedahl, Rikard LU and Sjoland, Henrik LU orcid (2024) 22nd IEEE Interregional NEWCAS Conference, NEWCAS 2024 p.208-212
Abstract

The anticipated introduction of multi-GHz channel bandwidths in 6G makes integrated passive baseband filters very attractive. This work presents techniques to obtain high stop-band attenuation in a compact 4.7-GHz 5th-order passive baseband filter. A lumped model of the filter inductors is derived, and a capacitive cancellation technique is proposed, along with techniques to reduce inductive coupling, which are verified using EM simulations. The proposed techniques improve the stop-band attenuation by up to 30 dB.
