Variability of UTBB MOSFET Analog Figures of Merit in Wide Frequency Range
Inter-die variability of analog figures of merit of ultra-thin body and buried oxide (UTBB) FDSOI MOSFETs was studied in a wide frequency range. We demonstrate that variability in the entire frequency range is small and does not exceed 5%, which is considerably less than in previously published results on SOI FinFETs. An effect of frequency on the analog figures of merit variability is discussed and preliminary explanation is proposed
