ANALOG DEVICES BUF-03's Simplified Schematic

General Description
The BUF-03 is the first very high-speed monolithic voltage follower.
Featuring performance previously unobtainable in a monolithic unit, it offers a combination of both exceptional speed and excellent input/output specifications. Implemented in an open-loop circuit employing source followers and emitter followers, the BUF-03 utilizes a quasi-quad FET input structure to optimize both speed and D. C. input characteristics.
On-Chip zener-zap trimming is used to achieve low offset voltage while careful biasing throughout results in excellent gain linearity over the full input voltage range

Applications for which the BUF-03 is well-suited include high-speed line drivers ...
