TEST CIRCUITS
APPLICATIONS
High-Speed Sample-and-Hold
In a fast sample-and-hold application, the analog switch
characteristics are critical. A fast switch reduces aperture
uncertainty. A low charge injection eliminates offset (step)
errors. A low leakage reduces droop errors. The CLC111, a
fast input buffer, helps to shorten acquisition and settling
times. A low leakage, low dielectric absorption hold capacitor
must
be
used.
Polycarbonate,
polystyrene
and
polypropylene are good choices. The JFET output buffer
reduces droop due to its low input bias current.
(see figure 5.)
Pixel-Rate Switch
Windows, picture-in-picture, title overlays are economically
generated using a high-speed analog switch such as the
DG613. For this application the two video sources must be
sync locked. The glitch-less analog switch eliminates halos.
(see figure 6.)
GaAs FET Drivers
Figure 7 illustrates a high-speed GaAs FET driver. To turn
the GaAs FET on 0 V are applied to its gate via S1, whereas
to turn it off, - 8 V are applied via S2. This high-speed,
low-power driver is especially suited for applications that
require a large number of RF switches, such as phased array
radars.
