These high-performance silicon micromachined linear accelerometers and
inclinometers consist of a sensor element and an ASIC packaged in a
3x3x0.9mm Land Grid Array (LGA). The sensor element is fabricated from
single-crystal silicon with proprietary Deep Reactive Ion Etching (DRIE)
processes, and is protected from the environment by a hermetically-sealed
silicon cap at the wafer level.
The KXTE9’s advanced, orientation-detection feature reports changes in
landscape, portrait, face-up, and face-down conditions. This sophisticated,
embedded algorithm eliminates the need for continuous data collection and
complex calculations by a microprocessor. With a few adjustable parame-
ters, the screen-rotation algorithm can be optimized for an intuitive user
experience. In addition to orientation detection, the KXTE9 features an ac-
tivity-monitoring function. This function reports changes in a device’s mo-
tion state, either moving (active) or not moving (inactive). A highly-
manufacturable product with consistent product performance across use
conditions, the KXTE9 operates across a supply voltage of 1.8V to 3.6V DC.
The sensor element functions on the principle of differential capacitance.
Acceleration causes displacement of a silicon structure resulting in a change
in capacitance. An ASIC, using a standard CMOS manufacturing process,
detects and transforms changes in capacitance into an analog output volt-
age, which is proportional to acceleration. The sense element design utilizes
common mode cancellation to decrease errors from process variation and
environmental stress. The voltage is digitized by an on-board A/D converter
and is accessed via an inter-interated circuit (I2C).
