Abstract
The invention relates to a high-speed output driver having at least one CMOS inverter (IN ), acting as an amplifier for high-frequency digital signals, which has an n-channel transistor (T ) and a complimentary p-channel transistor (T ) connected in series with it. According to the invention, switch means are provided, which are connected to sensor elements for detecting parameters of the transistors (T , T ), and which as a function of the detected parameters control or regulate the output current and the output resistance of the driver to a substantially constant value. In this way, a high-speed output driver with substantially constant outset conditions is made available. (FIG. )
