Simply put, inductors resist a change of current ... the higher the inductance, the higher the resistance to high speed demands for current. After years of knowing this relationship, but not ...

At some very high frequency, the inductor’s effective resistance ... architectures for gyrators that produce a floating virtual inductance, but those are rare because they take more components.

Studies published about integrated inductor-based SR using embedded inductors clearly show that this type of SR requires very high switching frequencies and finally turns out to be unattractive ...
