TI Logic Guide

  • input/output logic levels for various families

  • interfacing between supply voltages and families

2. Simulating C5 process inverter

Download to same location as your LTspice schematic: c5.txt (transistor models).

inverter start

  • draw schematic

  • include c5.txt models

  • set transistor sizes using parametric values

    • why is lambda = 0.3 μm instead of 0.25? drawn vs fabricated dimensions XL

  • DC input sweep

  • BUGFIX why parameters don’t affect results

  • fix model

  • change PMOS width with .step
