Hello,
I am a beginner with simulation in KiCAD and NGSPICE. This is a request for help with a VCO circuit that I have imported from LTSPICE where it works, but I’d like to learn how to do the simulation in KiCAD.
I have replaced all the symbols that pointed to an LTSPICE library with generic KiCAD symbols and run an ERC check, which now passes with 2 exclusions (for 2 hierarchical labels).
I have included the text .model statements for the transistors and Zener diode in the schematic. The model for the BB105B varicap diode can’t be found, but I have included an example. This example is from a post on the LTSPICE groups.io forum.
I need to get the potentiometer working on the schematic, and I have NOT run the simulation yet. I need to take this step by step. Can someone help? Thanks. JLH_TUNER_VCO.kicad_sch (91.1 KB)
PS I’m using KiCAD 8.05 on Windows 10. Should I be using resistor/capacitor symbols from a simulation library? If so, I will upload again later with an actual DC power supply included.
