Temperature-dependence of noise figure of monolithic RF transformers on a thin (20 /spl mu/m) silicon substrate

Abstract

We demonstrate an analysis of the effect of temperature (from -45/spl deg/C to 175/spl deg/C) on the quality-factor (Q-factor) and noise figure (NF) performances of monolithic RF transformers on both normal (750 /spl mu/m) and thin (20 /spl mu/m) silicon substrates. The results show that silicon substrate thinning is effective in improving the Q-factor and… (More)
