While designing low noise amplifier (LNA), we are using both passive feedback and active feedback. what are its importance and limitations of active and passive feedback, while designing LNA

Passive feedback means we are using R,L, C as the feedback elements in LNA

Active Feedback means we are using Transistor as the feedback element in LNA
