BUFFER WITH COMPENSATING DRIVE STRENGTH

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-weithed 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.
