Abstract :
The presented IC performs the high-voltage functions of an electronic subscriber line interface without the need for any transformers or relays. The challenges of SLIC integration stem from the combination of 150 V line feeding demands with 0.2% accuracy in a harsh environment. A new BCD-process, SPT170, together with appropriate circuit concepts (buffers with DMOS outputs, n-type supply voltage switch, accuracy by polysilicon resistors) yielded a 30 mm2 robust SLIC with excellent transmission properties
