ECE 558 Introduction to VLSI Design

ECE 658 (NTU IC740-A) VLSI Design Principles

Lecture 12 (Fall 2006)  

Sequential Logic

• Bi-stable device, SR
• Various Flip-flops, latches and registers
• Clocked SR FF
• Timing Definitions: setup, hold, propagation
• Definitions: edge-triggered vs. level-sensitive
• Charge-Storage devices
• Bi-stable devices
• Dynamic latches
• Static Latches, Keepers
