RLA/RFA Analog Arrays
December 1999
2(2)
Analog macrocells
The macrocells are made entirely of transis-
tors similar to the auxiliary transistors, but
partly hard wired in the bottom layer metal.
The macrocells are optimized for operational
amplifiers or comparators but can also be
configured as other functions. All macrocells
have programmable Iset for optimal speed
vs. power trade off.
Several configurations are caractarized and
are also available as schematic symbols,
simulation models and kit part components.
RLA40, 80, 120 and 160 consist of bipolar
macrocells. RFA120 also includes 8 BiFET
macrocells. These macrocells are optimized
for FET input operational amplifier.
One RFA120 macrocell configured as a
MOPA5 FET input Op Amp (TL082 type).
Breadboard
A big advantage with the RLA/RFA concept is
the available kit parts. A breadboard can be
made from kit part components. The circuit
can be tested with external circuitry and even
in the application before layout is started and
prototypes are made. The kit parts are pro-
duced using actual RLA/RFA arrays.
Both complete operational amplifiers, compa-
rators etc. as well as auxiliary transistors are
available. The kit parts are delivered with a
complete design kit also including design and
application manuals and simulation models.
Kit Part components are available. This one
includes quad MOPA2 (LM324 type).
