High gain, but not easy to control (18-Transistors)

thank you very much

[@paulpaulzadeh6172]

Is transistor voltage control or is it current control ¿?

[@AyazMehmood-yk5vc]

both, as Ic = beta*Ib and Ic = gm*vbe.

The BJTs are current controlled current controller, while the MOSFETS are voltage controlled current controller.

Input Base current control output collector current so current controlled device
