About MEMSMicroelectromechanical  systems (MEMS) is a process technology used to create tiny integrated devices or systems that combine mechanical and electrical components.They are fabricated using integrated circuit (IC) batch processing techniques and can range in size from a few micrometers to millimeters. These devices (or systems) have the ability to sense, control and actuate on the micro scale, and generate effects on the macro scale. MEMS technology is widely used today in many applications such as Mechanical (e.g Pressure sensors, Accelerometers, and Gyroscopes), Microfluidics (e.g Inkjet nozzles), Acoustics (e.g Microphone), RF MEMS (e.g Switches and Resonators), and Optical MEMS (e.g. Micromirrors).

About MEMS microphoneMEMS microphones are capacitive (condenser) in nature and employs advanced silicon micro machining technology to produce highly reliable and capable audio sensing capabilities that are integrated with specialized pre-amplification ASIC to provide high sensitivity, high signal to noise ratio output.

Digital MEMS microphones have a PDM

single-bit output with option for stereo

and they needs only 2 pins from the

controller in all configurations.

Analog MEMS microphones have

separate power terminal (Vc) compared

to standard ECM sensors and they are

simple to connect with only one external

component.
