Overview:
Decompensated amplifier is a unique type of amplifiers that provides higher bandwidth and faster slew rate. It has a minimum gain requirement. If you use the decompensated amplifier below the minimum gain stated on the datasheet, the amplifier becomes unstable. However, this limitation will not limit your design! It has many advantages if it is used correctly specially for high gain applications where the ratio of overall bandwidth to supply current is important! Other applications that would benefit from Decompensated Amplifiers are High Speed ADC Interface, Medical Systems, and Wide Band Communications. In this seminar, we will discuss the internal circuitry and why we can get higher bandwidth and faster slew rates with less supply current, its application, and compensation techniques when using decompensated amplifiers.
