ltspice simulation

  1. Simple sawtooth generator schematic simulation question

    I've tried to play a bit with the passives values of this circuit and I obtained max 2kHz freq signal. Do you think that using this circuit I can obtain a 70kHz signal? Would you suggest another kind of simple circuite for the purpose? Thanks

    Unused port in hierarchical block in LTspice

    Hello everyone, I'm doing parasitic capacitance simulation of a SiC half bridge power module. I made a hierarchical block which represents the MOSFET in each switching position. But when I tried to run the simulation, a warning occurred, saying the Tj_MOSFET port in the block was unused, I...
  3. Need Spice model for D965 npn transistor to simulate in Ltspice

    Dear all I've a bunch of D965 and want to use in various hobby circuits. While designing I use Ltspice simulation to get idea of the circuit's behavior at different conditions. Unfortunately I don't have spice model of D965 to use in Ltspice. I searched through google- with no luck! Can...
