Abstract

A transmission line driving circuit for being one-to-one corresponding connected to an ATM-LAN physical layer of a receiving circuit through a transmission line, which comprises: an output driving circuit having a pair of transmission terminals, resistances separately connected to the pair of transmission terminals for adjusting the output impedance, a filter serially connected to the resistances, and a transformer the primary side of which being connected to the output terminal of the filter and the secondary side of which being connected to the transmission line; the output driving circuit comprising: CMOS output stages composed of first and second pairs in which PMOS transistors and NMOS transistors are serially connected; the source of the PMOS transistor and the source of the NMOS transistor being coupled with power source voltage and ground potential (Vss), respectively; the common drain of the MOS transistor composing the first pair and the common drain of the MOS transistor composing the second pair being coupled with one transmission terminal and the other transmission terminal, respectively; the first pair and the second pair of the CMOS output stage being made to perform pushpull operations in the opposite phase with each other.
