  1. 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.

  2. Do any of you have a SMU that can reach 1kV level? I’d like to do a simple (remote) experiment but my SMUs only reach 210V. Keithley 2410, 2470 or 2657 models would be ideal.

    We are investigating switching losses of power transistors and we need to measure the output capacitance in a particular way.
