ABSTRACT:
A circuit for compensating a cascode amplifier has been provided. The circuit includes a capacitor and an inductor for enhancing the stability of the amplifier and for extending the usable frequency range of the amplifier by maintaining the group delay of the amplifier substantially constant over a large frequency range. With such a compensated amplifier, an improved CTB distortion performance in the upper operating frequency range of the amplifier is achieved with increased stability. In other words, the bandwidth of the amplifier is extended with improved stability and distortion performance.
