Logic Gates Using Diodes and Transitor

Logic gates are building blocks of the digital system. In this post, we will see how basic digital gates can be made with the help of diodes and transistor.

Universal Logic Gates NAND and NOR

With the help of NAND and NOR gate, we can implement any logical realisation that's why these gates are known as universal gates.

Digital Electronics Arithmetic Circuits

Adders are the combination circuit used for adding two or three one bit binary numbers. A combinational circuit is that circuit which is implemented using the boolean circuit.

Ripple Carry Adder

Ripple carry adder is a combinational circuit that can perform addition operation of two n-bit binary numbers. It accepts two n-bit binary numbers as an inputs, performs addition of both the binary numbers and generated it's addiiton as an output.

Carry Look Ahead Adder

Carry Look Ahead Adder is digital circuit which performs n-bit addition operation. Here we only use generator and propagator to computes carry out.

Multiplexer in Digital Circuit

Multiplexer in digital circuit has many inputs (m) with only one output and it is denoted by m:1 MUX where m is the number of inputs. It selects only one input (one input is connected to the output) based on the select line.

Adder Subtractor in Digital Circuit

Addition and subtraction operation is the fundamental operation performed in arithmetic and logical unit of CPU.
