I have simulated the inverter using LTSPICE...I m using this tool for the first time...I want to
1. measure the inverter delay
2. plot delay vs supply voltage
May i know the procedure to perform these two steps..
1. Stimulate the inverter with a steep square pulse
2. Sweep (.step) the supply voltage - and possibly the corresponding voltage values of your stimulation source, and those between which you want to measure the delay - e.g. between 10 & 90% of the supply voltage
3. Run transient simulations for each voltage .step for at least 2 square pulse edges, with enough time resolution
4. Use appropriate .measure statement to measure the delays
5. Use appropriate .option to plot the measured delay values vs. supply voltage
