Explain the various Capacitances associated with a
transistor and which one of them is the most prominent?

Answer Posted / narendra

g = gate, s= source, d= drain and b = bulk.

Cgs, Cgd, Cgb, Csd, Csb, Cdb. Out of this the largest is
the Cgs becoz its value is linearly proportional to width
of transistor and the Gate oxide which is the di-electric
for this capacitance is the one which is engineered to have
more dielectric constant and less thickness.
