LVT (Low Voltage Technology) a

LVT (Low Voltage Technology) and ALVT (Advanced LVT)

Philips Semiconductors has introduced two low voltage families
optimized for backplane driving applications: LVT (Low Voltage
Technology) and ALVT (Advanced LVT). The purpose of this note is
to provide better insight into both families for optimal use by
designers in their applications.
New circuit techniques have been pioneered that give LVT and
ALVT their unique properties, some of which will be discussed in
detail.
Both families are fabricated using QUBiC, an advanced BiCMOS
process, where the best properties of bipolar transistors (fT=17GHz)
are combined with optimized CMOS (0.65 – 0.8 ). In addition,
special components can be built in such as Schottky diodes and
zener diodes for specific requirements. QUBiC processing enables
extremely short propagation delay times combined with low power
dissipation, low noise and high output drive. The process also
allows very low temperature dependency of AC and DC
characteristics.
The excellent properties available in the world’s first Advanced
BiCMOS family, Philips Semiconductors’ 5V ABT family, are now
taken to even greater heights in LVT and ALVT.
