What does CAD stands for? CAD stands for Computer Aided Design. What is CAD? What Types of CAD Tools are Used for Designing a Digital System? CAD is used for 2D or 3D modelling of structures which uses unique and Read More …
What happens when you apply asynchronous inputs to flip flops? Regardless of the state of the clock input, asynchronous inputs on a flip flop have control over the outputs (Q and not-Q). These inputs are referred to as clear and Read More …
Sequential circuit Discuss the Design Steps for Analysis of Asynchronous Sequential Circuits? Sequential Circuits are those in which the current output is dependent both on the current input and the previous output. It is a memory-equipped combinational circuit. Asynchronous circuit Read More …
Introduction to Power Dissipation in Logic Gates How the Power is Dissipated in Logic Gates? The amount of electric power dissipated by the transistors in an electric circuits is important to be considered. This is because of the fact that Read More …
Silicon is actually a semiconductor material which usually do not conduct under normal conditions. Conduction can take place under special conditions. A transistor is fabricated by adding purities in the substrate such that one part of the layer has excess of either positive or negative charges. Negatively charged region is called the n-type region and positively charged region is named as p-type region. The structure of NMOS transistor is shown in the figure below.
In CMOS circuits, pull up device is replaced with a pull up network (PUN) which is designed using PMOS transistor. This arrangement should be such that the circuits implemented by PDN and PUN should be the complement of each other.
Explain working of Programmable Logic Controller (PLC). Programmable logic controller is present in almost every industry. As the name suggests, we control digital and analog logics by embedding a program on hardware or module of the system.
What is the Pulse Width Modulation? What are the types of Pulse Width Modulation Technique (PWM)? Pulse Width Modulation(PWM) technique is used for controlling the AC output of power electronics converters. In this technique duty cycle can be varied from Read More …
SPLDs, CPLDs Vs FPGA In this article I will discuss General Structure of Field Programmable Gate Arrays. A wide range of logic circuits can be implemented using the 7400 series, SPLDs, and CPLDs. With the exception of CPLDs, these devices Read More …
Transistor Switches What are the Transistor Switches? Transistors are used in logic circuits. We can presume that a transistor is used to understand how logic circuits are created. It works as a simple switch. A switch controlled by a logic Read More …
