发明名称 Methods and apparatus for low voltage control of a subscriber line interface circuit
摘要 In one embodiment, the present invention includes a device having a low voltage SLIC to perform SLIC functions at a low voltage and to provide metallic and longitudinal currents to a high voltage SLIC. The low voltage SLIC may be designed based on an operational amplifier cell architecture, and the high voltage SLIC may receive the metallic and longitudinal currents and generate first and second amplified output currents therefrom.
