upgrading PI controller into a current driver for a YIG
« on: January 23, 2025, 09:50:36 pm »
There is a PI controller with certain AC behavior. I need to use this PI controller in order to drive a coil (current controlled oscillator) of 1.5 µH inductance. For DC behavior at 10 mV input I need 50 mA current on the coil at most. PI controller has proportional and integrator property.

How can I convert this behavior into a driver circuit?

UPDATE:
I have tried to drive the inductor threw NPN.
How do i connect it to the Integrator?
Thanks.
