A 5 kV HBM Transformer-Based ESD Protected 5- 6 GHz LNA

 

Abstract

Integrated designs in deep-submicron CMOS require ESD protection for their I/O pins. Since CMOS scaling drastically lowers the breakdown voltage of a MOS transistor, the available design window for ESD protection is narrowing. An inductor-based ESD protection offers superb protection but is severely area consuming. In this paper we propose a transformer-based ESD protection for inductor-based LNAs. We demonstrate that the proposed technique offers excellent ESD protection and RF performance without the loss of area. Keywords: LNA, ESD protection, transformer, low area, CMOS.
