Abstract: Here for the first time, we report on the characterization and analysis of random telegraph noise (RTN) in silicon-germanium (SiGe) channel pMOSFETs without a silicon-cap layer. A detailed analysis of traps causing two-level RTN is presented. The trap parameters and RTN magnitude are computed. It was observed that the impact of RTN is similar when compared with silicon channel pFETs from a similar process node with a comparable ${T}_{\text{inv}}$. [ABSTRACT FROM AUTHOR]
