Introduction
The introduction of current feedback amplifiers, such as the LT1223, has significantly increased the designer’s ability to solve difficult high speed amplifier problems. The current feedback architecture has very high slew rate and the small-signal bandwidth is fairly constant for all gains. Current feedback amplifiers are used in broadcast video systems, radar systems, IF and RF stages, RGB distribution systems and many other high speed circuits.
As with any new circuit, there are several new ...
