Abstract :
The paper compares two types of ESD-protection suited for the protection of CMOS low-noise amplifiers. This comparison is illustrated by the design and measurement of two high performance LNA prototypes. The first amplifier, with diode protection, targets the GPS L1 band at 1.57 GHz. It features a very low noise figure of 1.3 dB and a gain of 16.5 dB. The second amplifier was designed for 5 GHz wireless LAN applications and uses inductive ESD-protection. This prototype has a power gain of 20 dB and a noise figure of 3.5 dB. Both amplifiers surpass the industrial 2 kV HBM specification.
