| 摘要 |
An integrated circuit output buffer adapted for impedance matched coupling at a first temperature and at a second lower temperature to a transmission line (40) having a characteristic impedance at the first temperature, includes an output terminal (38) adapted to be coupled to the transmission line (40), and an output stage (14) having a first output impedance at the first temperature and a second lower output impedance at the second temperature. A compensation resistor (16) has a lower temperature coefficient of resistance and is provided for coupling the output stage (14) to the output terminal (38). |
