摘要：
A compensating buffer providing both course tuning on initialization and fine-tuning during operation is disclosed. The course tuning is provided by a plurality of binary-weighted driver legs which are selected during initialization. The fine-tuning which is selectable during both initialization and during operation is provided through linear-weighted biasing. The linear-weighted biasing is simplified through the use of a digital-to-analog converter.
