As judged from expression (1), the turn-off time t
off
is affected by collector-base capacitance C
C-B
, D.C. current amplification
factor h
FE
, and load resistance L
R
. In actual circuit design, C
C-B
and h
FE
are fixed. Accordingly, the turn-off time is significantly
affected by the resistance of load R
L
.
Graph 1 shows the relationship between response speed (t
on
,t
off
) and load resistance (R
L
) in typical emitter follower (test circuit 1)
having a load resistance of 100
.
