Technology

QUATEK offers the first CMOS MEMS differential microphone that use in smartphones and other speech devices.

They are high-performance and enable acoustically rich experiences for any application – from smartphones to Internet of Things (IoT) devices and connected automobiles.

QUATEK differential microphone operate on a completely different principle from all other MEMS and electret condenser-style audio devices. QUATEK’s MEMS differential microphone directly convert sound wave energy into an differential electrical signal.

QUATEK technology is compatible CMOS process with a proven CMOS process. Beyond just delivering an excellent signal-to-noise ratio (SNR) and common-mode rejection ration(CMRR), QUATEK microphone is stably matched, making them uniquely suited for array beamforming in smartphones, tablets, smart home devices and other connected products.
