  • High power, from milliwatts up to >100W
     

Technology Overview - Audio

Noise cancellation

Active Noise Cancellation (ANC) systems from ams provide high levels of noise attenuation while producing very high-quality audio output.

 

The ams ANC technology enables manufacturers of noise-cancelling audio products to save space and power and reduce system cost.

 

Technology Overview - CMOS

CMOS imaging

ams continuously develops new technology to improve the performance of its CMOS image sensors. These technology improvements support both custom CMOS image sensor developments and standard, off-the-shelf CMOS image sensor products.

 

Technology Overview - Advanced Packaging

Advanced packaging

Chip packaging technologies developed by ams help its state-of-the-art optical devices and position sensor products to achieve very high precision and low-noise performance.

 

Advanced packaging technologies from ams include:

  • Wafer-level optics, which enable the precise fabrication of lenses for miniature light sources and detectors
  • Through-silicon vias, which radically reduce the height of an optical IC package and eliminate the need for wire bonds
  • System-in-Package (SiP) technology – ams integrates complete position sensor assemblies into a single SiP to save space and eliminate a board assembly process for its customers
     

Technology Overview - MOX

Metal-oxid sensors

Metal-oxide (MOX) gas sensing technology from ams offers very high tolerance of siloxanes and gives users the most robust platform for the development of reliable air-quality monitoring and gas detection products.

 

The superior ams technology is backed by more than 12 years’ experience of supporting customers with the real-world implementation of MOX-based gas sensing technology.
