Let's Program the Transistors
Problem Statement: Design a circuit for an edge triggered 4-bit binary up counter (0000 to 1111). When it reaches “1111”, it should revert back to “0000” after the next edge. Use positive edge triggered D flip-flop (shown in the below figure) to design the circuit. Pin Input / Output Description D Input Data Input CLK…

Flip-Flop (FF) and Latch are digital electronic circuits that are used to store information in bits as they have two stable states. One FF or latch can store 1 bit of information. FF is a circuit that can be made to change its state by applying signals to one or more control inputs and will have…
Combinational and Sequential circuits are the most essential concepts to be understood in digital electronics. Sequential logic is a type of logic circuit whose output depends not only on the present value of its input signals but on the sequence of past inputs. Combinational Logic Circuits Sequential Logic Circuits Output is a function of the…

I got an Interview call from Tech Mahindra VLSI Dept, and I am sharing my Interview Experience here. The Interview was telephonic and and was about 55 minutes long. They asked for core technical questions related to HDL (Hardware Description Language) which you can answer correctly only if you have some basic work experience with…

Microcontroller is termed as “Computer-on-a-Chip“. It is named so, because not only the CPU, but RAM, ROM, I/O ports, Timer/Counter, Serial I/Os all are put together on a single microcontroller chip. Microcontrollers are task specific and are essentially used for making Embedded Systems. The above image shows very few examples for the application of microcontrollers…
Hello everyone, this is my interview experience at the on-campus placement drive of Aricent Technologies. Aricent visited our campus on 30th September 2015. Being from the Electronics & Communication Engineering (ECE) branch, I was very much excited about its visit, as it is a core company which deals with “Communications Infrastructure” and “Embedded Systems“. The first…

These are some simple steps which can be used to do the power analysis of a design using Xpower Analyzer which comes readily available in the ISE free web pack. ## Make sure your circuit can be synthesized. Then under the implement design option in the project navigator, Place and Route the design. ## The…
When someone start dealing with Microprocessor; a very common doubt always strikes out in the initial phase: “What is the difference between Microprocessor and Microcontroller?” Let’s Define both microprocessor and microcontroller and then we will compare them. Microprocessor: We mean by a microprocessor that all the components of a CPU (Central Processing Unit): ALU (Arithmetic Logic…
