2 Sequential Circuit Design

This chapter describes flip-flops (F/F), registers, counters, and the finite state machine. F/Fs are part of all sequential circuit designs [1]. A sequential logic circuit can be designed using flip-flop and combinational logic circuits. Registers and counters are commonly used in digital systems. The designs of all flip-flops are described in the next subsection.

2.1 Flip-flops (F/F)

F/Fs are a single-bit binary storage device, that have two states, one is pre-set and the other is clear state. It has two outputs and these are complementary to each other. Each flip-flop also has three control inputs. The first control signal is the clock; it is used to synchronize the circuit. Other control signals are set and reset; these are used to set or reset the value of the corresponding flip- flops. These are also used to design registers, counters and other sequential circuits. There are four types of flip-flop.

2.1.1 S-R F/F

S-R is the basic F/F; it means other F/Fs can be designed using this F/F. It has two inputs and two outputs. It has an indeterminant condition (or undefined) when S = 1, R = 1. F/Fs are designed with the help of logic gates and the clock.

The S-R F/F designed with NAND-gate and with clock input is depicted in Figure 2.1.

A truth table of S-R F/F is given in Table 2.1.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
