Consider the fundamental characteristics of the logic gates presented: ability to connect to one or two input wires - ability to connect to one output wire - ability to receive a value from a connected input wire - ability to transmit a value to a connected output wire - ability to compute correct output value, given current input value(s) Now, the notGate is something of an anomaly since it is the only one that takes File Size: KB.

For input X and Y, the output of the OR gate will be X.Y which is fed as input to the NOT gate. So the output of NAND gate is given by dyku.xn---22-6cdxiysjjhmldau9o.xn--p1ai is equal to X+ Y X F = X. Y F = X.Y Y The logical symbol for two-input NAND gate and the truth table is given below. X F = X.Y Y. XOR (Exclusive-OR) Gate. logic gate circuit are its layout area, delay, and power consumption.

We will concen-trate our analysis on the inverter because it is the simplest gate to analyze and its anal-ysis extends straightforwardly to more complex gates.

Static Complementary Gates Gate Structures. Download the pdf version of these notes. Introduction. Logic gates process signals which represent true or false. Normally, the positive supply voltage +5V represent true and 0V represents false. Other terms which are used for the true and false states are shown in the table. Given a truth table that specifies a logic circuit’s behaviour, design the equivalent circuit.

– Example: three-input circuit • Sum-of-product technique: – Group all rows with an output of f=1 into a single AND term (product) – Combine these AND terms with a single OR gate (sum) •Note:All truth tables can be converted into gate form by using this dyku.xn---22-6cdxiysjjhmldau9o.xn--p1ai Size: KB. The simplest, non-trivial logic gate that satisﬁes rule 1 is the logic gate composed of a single NFET (to pull the output down) and a single PFET (to pull the output up).

This arrangement was already described in Figure However, the conﬁguration of Figure (e) violates rule 2 and the conﬁguration of Figure (d) violates rule 3. The basic logic gates arethe inverter (or NOT gate), the AND gate, the OR gate and the exclusive-OR gate (XOR). If you put an inverter in front of the AND gate, you get the NAND gate etc.

3 One ofthe common tool in specifying a gate function is the truth table. All possible combination of. A logic gate is a circuit with one or more input voltages but only one output voltages. logic gates are fundamental building blocks of the digital system. NOT, OR, and AND Gates are the basic types of gates. The interconnection of gates to perform a variety of logical operation is called logic design. •A gate is a device that performs a basic operation on electrical signals • Gates are combined into circuits to perform more complicated tasks.

It is an electronic circuit having one or more than one input and only one output. The relationship between the input and the output is based on a certain logic.

Based on this, logic gates are named as AND gate, OR gate, NOT gate etc. AND Gate. Simple digital logic gates can be made by combining transistors, diodes and resistors as discrete components. Let us investigate some of such circuits using Diode-Resistor Logic (DRL), Diode-Transistor Logic (DTL) and Transistor-Transistor Logic (TTL) as described below.

logic gate is represented by a different picture, like the ones shown below. NOT • NOT is the most simple logic gate. • All it does is take in an input that is either ON or OFF and spits out the opposite.

• So for a 1 it will give a 0, and for a 0 it will give a dyku.xn---22-6cdxiysjjhmldau9o.xn--p1ai Size: KB. Logic gate Identify the types of logic gates which do the following (there is more than one type of gate for each of the following rules!): • B = A when Control is high • B = A when Control is low • B = A when Control is high • B = A when Control is low Also, explain how an understanding of this can be helpful in troubleshooting faulted logic dyku.xn---22-6cdxiysjjhmldau9o.xn--p1ai Size: 62KB.

Page 16 NAND GATE The NAND gate is made up from a combination of an AND gate. False represents 0, and true represents 1. Depending on the type of logic gate being used and the combination of inputs, the binary output will differ. A logic gate can be thought of like a light switch, wherein one position the output is off -- 0, and in another, it is on -- 1. Logic gates are commonly used in integrated circuits.

Basic logic gates. There are seven basic logic gates: AND, OR, XOR. interpreted by any gate receiving this signal as LOW or LOGIC 0. 0V ZERO VOLTS is the IDEAL value for LOGIC 0. 5V FIVE VOLTS is the IDEAL value for LOGIC 1.

A gate, apart from performing its LOGIC FUNCTION, serves as a BUFFER AMPLIFIER to REGENERATE "WEAK" (not so ideal) input signals into "STRONG" (nearly ideal) output signals.

Figure 1: Latch R-S Flip Flop Using NAND and NOR Gates. To describe the circuit of Figure 1(a), assume that initially both R and S are at the logic 1 state and that output is at the logic 0 state.

Now, if Q = 0 and R = 1, then these are the states of inputs of gate B, therefore the outputs of gate B is at 1 (making it the inverse of Q i.e. 0). Topic Notes: Digital Logic gate sink source ground gate potential >> 0 0−resistance wire gate potential = 0 This is a ﬁeld-effect transistor (FET). For physicists, this is a “continuous” device – a variable resistor, maybe an ampliﬁer.
