Why would we prefer an active inductor over a passive inductor in RF integrated circuit design?

I personally prefer active inductors when I'm working on compact RF circuits. Passive spiral inductors take up a lot of chip area, and once you fabricate them, their inductance is fixed. That’s not ideal when you need flexibility during tuning or prototyping. Active inductors, on the other hand, are tunable — I can tweak the inductance just by changing bias currents. That alone saves a ton of design hassle.
