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
polypropylene are good choices. The JFET output buffer
reduces droop due to its low input bias current.

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 S
to turn it off, - 8 V are applied via S
low-power driver is especially suited for applications that
require a large number of RF switches, such as phased array
radars.
