TEMPERATURE COMPENSATED OUTPUT BUFFER ABSTRACT OF THE INVENTION An integrated circuit with temperature compensated output buffers which are adapted for impedance matched coupling to transmission lines when operated at either room temperature or at a cryogenic temperature (e.g., immersed in liquid nitrogen). The output buffers include output terminals which are adapted to be coupled to the transmission lines. Output stages of the output buffers have an output impedance which is less than a characteristic impedance of the transmission lines, and are characterized by a temperature coefficient of resistance. Compensation resistors which have an impedance less than the characteristic impedance of the transmission lines, and are characterized by a relatively low temperature coefficient of resistance, couple the output stages to the output terminals. 3180N 24 SEP 86
