X-Fab adds low-noise 180nm transistors for audio and sensor amps.

Aiming at sensor interfaces, semiconductor foundry X-Fab has created more low-noise transistors for users of its 180nm XH018 mixed-signal CMOS process. There are three: 1.8V NMOS, with an eighth of the nose of its standard XH018 equivalent 3.3V NMOS, with a tenth 3.3V PMOS, with half “all of which offer drastically reduced flicker noise compared ...
