摘要：
In integrated circuits the delay of the signal transitions has to lie within specified limits. This delay is partly determined by variations in the manufacturing process (process scatter). To compensate for the effect of this scatter a load capacitance 28 (figure 1) is connected via a switching element (26) to a node which is to be influenced in the integrated circuit. The switching element 26 receives a reference voltage VR1 which is dependent on the manufacturing process and is generated by reference source 2 , so that the node capacitance 26 is connected to the said node for a longer or shorter time, depending on the process scatter.
