Electronics idea.
There are opamps with bipolar junction transistors (BJT) in the input stage.
There are others with junction field-effect transistors (JFET) in the input stage.
There are yet others with metal-oxide semiconductor field effect transistors (MOSFET) [1] in the input stage.
Idea: find an application for the bizarre possibility of an opamp with insulated-gate bipolar transistors (IGBT) in the input stage. This is more stunt-designing than anything practical.
[1] IIUC, "CMOS" opamps are really just MOSFET-input opamps. I'm not sure why the process technology name is more commonly used rather than the device type as is universally used for BJT and JFET input opamps.
