The rapid development of wireless communication system has led to pressing need for highly linear amplifier design and implementation as amplifier is one of the most critical devices in transmit and receive chain. In recent years, a number of new and emerging amplifier linearization techniques using special distortion correction have been receiving more and more attention due to their significant advantages. One of the techniques is the negative impedance compensation. The design results showed that high gain, good linearity and wider bandwidth can be achieved by using the novel compensation method. However, as some kind of feedback can be introduced when applying the negative impedance compensation, the stability of the whole system should be investigated carefully. In this paper, stability analysis and stabilization have been performed for the amplifier with negative impedance compensation. The simulation results showed that stable circuit behaviour can be achieved by using the capacitive compensation in the negative impedance circuit.
