Computer-aided design and optimization of a broad-band high-frequency monolithic amplifier

A monolithic wide-band amplifier for applications in counters from dc to UHF frequencies has been realized. The use of computer-aided design techniques, using a transistor model, and a broad-band feedback configuration has resulted in a monolithic amplifier that previously could only be constructed in hybrid form. This paper describes the development of a new high-frequency transistor model and a dc-coupled monolithic high-frequency amplifier that incorporates a final masking step option to obtain a maximally flat response over a 700-MHz bandwidth.
