Abstract :
This paper presents the high voltage building blocks of a Subscriber Line Interface Circuit (SLIC), designed for short loop applications. The circuits are implemented in a 5 V 0.8 μm BiCMOS process using high voltage extended-drain MOS transistors, fully compatible with the low voltage technology. According to the short loop requirements, this SLIC is designed to operate with a 30 V power supply and have 30 mA loop driving capability With less than 1 mm2 area and 70 mW idle power, this circuit can be easily integrated with high-density low-voltage circuits to implement a single chip SLIC
