Lecture 8 (Fall 2006)

• More on CMOS Static Logic Gates:
• Delay Analysis of Complex Gates: What is Ron? Sizing, Adder Example
• Intro to Ratioed Logic: Pseudo-NMOS, etc., DC characteristics,
• Pass Transistor Logic: DC, timing, Adder Example, optimal insertion of buffers

Coming up in next lecture
