Demystifying Piezoresistive Pressure
Sensors
Semiconductor components that use new signal processing techniques for piezoresistive
pressure sensors have enabled precise, automatic, and low-cost electronic compensation of
the standard error parameters. The resulting simplification and convenience have opened a
wide field of new applications, including the use of bridge sensors for properties other
than pressure.

Five Ways of Monitoring Electrical Current
Current measurement is frequently used in the operation of electronic instrumentation.
This tutorial examines resistive current sensing, I-V converters, magnetic current
sensing, closed-loop current sensors, and current transformers.

Understanding Frequency Domain
Measurements
There are times when analyzing signal components in the time domain just doesn't provide
the whole picture. On the other hand, the frequency domain offers an easy way of accessing
the information you need.

Spray Coating for MEMS, Interconnects, and
Advanced Packaging Applications
MEMS devices with extreme topography in height and size or with square-shaped substrates
can be covered with a uniform resist layer that meets the requirements of subsequent
photolithographic processes using advanced spray-coating technology.
