Assignment 3

Turn in your assignment on WebCT. Your report should be a Microsoft Word document. Upload all appropriate computer files associated with the assignment, such as SPICE .asc files and Excel spreadsheets.

Download: AMI-C5 technology files

  1. Use spice to generate a set of I-V curves for a NMOS transistor using the CMOSN model in ami_c5.lib. Make the transistor W/L = 1.8mm/0.6mm. Transfer the curves to an excel file and plot the results in excel.

  2. Use spice to generate a set of I-V curves for a PMOS transistor using the CMOSP model in ami_c5.lib. Make the transistor W/L = 16mm/1.6mm.

  3. Use spice to find the current and voltage shown for two NMOS transistors in series, shown below (VDD = 5 volts). Include the proper body connections (not shown). Make the transistors W/L = 5/2, meaning W = 1.5 mm and L = 0.6 mm.
