NOTE 1
The switching characteristics shown above were measured using
a test circuit similar to Figure 5. At the beginning of the switching
interval, the gate voltage is at Gate Supply Voltage (V
GG
). The
DrainSource Voltage (V
DS
) is slightly lower than Drain Supply
Voltage (V
DD
) due to the voltage divider. Thus Reverse Transfer
Capacitance (C
rss
) of GateDrain Capacitance (C
gd
) is charged to
V
GG
+ V
DS
.
During the turnon interval, GateSource Capacitance (C
gs
)
discharges through the series combination of R
Gen
and R
K
. C
gd
must
discharge to V
DS(on)
through R
G
and R
K
in series with the parallel
combination of effective load impedance (R’
D
) and DrainSource
Resistance (r
DS
). During the turnoff, this charge flow is reversed.
Predicting turnon time is somewhat difficult as the channel
resistance r
DS
is a function of the gatesource voltage. While C
gs
discharges, V
GS
approaches zero and r
DS
decreases. Since C
gd
discharges through r
DS
, turnon time is nonlinear. During turnoff,
the situation is reversed with r
DS
increasing as C
gd
charges.
The above switching curves show two impedance conditions; 1)
R
K
is equal to R
D’
which simulates the switching behavior of
cascaded stages where the driving source impedance is normally the
load impedance of the previous stage, and 2) R
K
= 0 (low
impedance) the driving source impedance is that of the generator.
