Design of an All-Digital LVDS Driver

This paper presents an all-digital low-voltage-differential-signaling (LVDS) driver design for Serial Advanced Technology Attachment II. A simultaneous-switching-noise reduction technique and an autocalibration mechanism are implemented to suppress switching noise and to handle process and environmental variations. The circuit is implemented in a 0.18-mum 1P6M CMOS process with a core area of 0.072 mm
