fact, with a purelyresistive load connected to V
s
/2
no parasiticelements interferesignificantly.
The waveformcan be significantly less easy to in-
terpret if the load has not the perfect symmetry of
that case, as showed below. For instance, it is
enough to connectthe resistiveload to ground, or
to V
s
– as figure 5 and 6 – show to hide some of
the switching phasesdescribed.
If the load is connected to ground, the waveform
stays stuck to ground as long as the output stage
is in high impedance; viceversa when the load is
connected to V
s
the waveform will linger close to
the supply voltageas long as possible.
If an output load made of an inductorand a resis-
tor in series is used, the inductive kick at the be-
ginning of every output transition generates the
equivalent effect of an ”anticipated” switching
when the inductor can discharge; while the
switching looks ”delayed” if the output transition
tends to initiate a chargingphase (see figure 7).
With a load almost free from parasitic elements,
the waveforms resemble the ones of the purely
resistivecases.
With a real, more composite load, the effect of the
inductive kick in comparison to the resistive load,
would be moreapparent.
With a capacitor and a resistor in parallel as a
load, another type of waveform can be seen (re-
ported in figure8).
As long as the output stage stays in the transient
high impedance state, the output voltage will fol-
low the classic exponential law of an RC relaxa-
tion.
As soon as the other transistoris switched on and
takes charge, the waveform is quickly
broughtto its steady state value.
From the above it is possible to see how the
switching times, inherently very fast, of the output
stages,may be difficult to identifyin a waveformif
the output load is not accurately taken into con-
sideration.
Figure 9 show typical switching waveform for in-
puts and outputs.
