In a CE amplifier, thermal runaway is unconditionally avoided if

A. \({{\rm{V}}_{{\rm{CE}}}} = \frac{1}{2}{\rm{\;}}{{\rm{V}}_{{\rm{CC}}}}\)
B. \({{\rm{V}}_{{\rm{CE}}}} > \frac{1}{2}{\rm{\;}}{{\rm{V}}_{{\rm{CC}}}}\)
C. \({{\rm{V}}_{{\rm{CE}}}} < \frac{1}{2}{\rm{\;}}{{\rm{V}}_{{\rm{CC}}}}\)
D. \({{\rm{V}}_{{\rm{CE}}}} = \frac{1}{{\sqrt 2 }}{\rm{\;}}{{\rm{V}}_{{\rm{CC}}}}\)
Answer» D. \({{\rm{V}}_{{\rm{CE}}}} = \frac{1}{{\sqrt 2 }}{\rm{\;}}{{\rm{V}}_{{\rm{CC}}}}\)
