Application Information
Video Amplifier with Reduced Size Output
Capacitance
If you have a video line driver Z = 75
Ω, the DC decoupling
capacitor could be relatively large.
=
f = 10Hz, R = Z = 75
Ω,
C = 132F
By using the circuit below, C could be reduced to C2 = 22F.
FIGURE 30. VIDEO-
The test result is shown on Figure 30.
By selecting a different value for C1, we could reduce the
effect, created by C3 R3 and get flat response from 16Hz
with an 1/5 value, price and size output capacitor. There is
another, very important issue by using high bandwidth
amplifiers.
In the past when the bandwidth of the operational amplifier
ended at a few hundred kHz even at few MHz, the power-
supply bypass was not a very critical issue, since a 0.1F
capacitor “did the job”, but today’s amplifiers could have
bandwidth, what used to be reserved for microwave circuits
not to long time ago.
Therefore that high bandwidth amplifiers require the same
respect what we reserve for microwave circuits. Particularly
the power supply bypass and the pcb-layout could very
heavily influence the performance of a modern high
bandwidth amplifiers. It could happen above a few MHz, but
it will happen above 100MHz, that the capacitor will behave
like an inductor.
