Single Event Effect Analysis of SiGe
Low Noise Amplifier
Manel Bouhouche, Saida Latreche
This paper analyzes the single event transient (SET)
response of low noise amplifier (LNA) designed using SiGe het-
erojunction bipolar transistors (HBT). To verify the radiation
tolerance of the proposed LNA, a total of four cascode configu-
rations were designed. Comprehensive mixed-mode simulations
were performed to evaluate the SET susceptibility of considered
LNA cascode configurations, and we have analyzed how the strike
parameters affect their output response. In this fact the strike po-
sition, linear energy transfer (LET), and track radius, were var-
ied, and the resulting transients were compared for the different
LNA configurations. Through this study, the potential capability
of the inverse mode SiGe heterojunction bipolar transistor (HBT)
in LNA radiation tolerance was confirmed for various strike op-
erating conditions. It has been demonstrated that the single event
sensitivity was reduced for LNA employing inverse mode SiGe
HBT for strike device. The strike influence on the different LNA
configurations response depends on strike LET, where a reduced
SET variation is observed for high LET
