Digital Circuit Design with an Introduction to CPLDs and FPGAs

Chapter 8: Sequential Logic Circuits


This chapter is an introduction to sequential logic circuits. These are logic circuits where the output(s) depend not only on the input(s) but also on previous states of the output(s). It begins with a discussion of the different types of flip flops, and continues with the analysis and design of binary counters, registers, ring counters, and ring oscillators.
