Apart from being accustomed to electronics and its innovation ,I am also a Linux and open source maniac.
Ring counter is a sequential circuit made up of flip flops in which the output of the final flip flop is again fed back a input to the first flip flop. The shifting operation is controlled by the clock signals. Here a 4-Bit Ring Counter is implemented and its verilog code along with the test … [Read more...]
What is USB ? USB stands for Universal Serial Bus. It eliminates need of add-in cards and separate power supplies and its hot swapping capability allows users to easily attach and detach peripherals.They are the single most portable data backup device widely used today. A USB Flashdrive is the … [Read more...]
The Idea !!! The revolutionary idea of using paper as a battery was striked to some researchers at Stanford University few yeas back and their experiments in this domain proved fruitful recently concluding that it is possible to use the plain paper as a source of power. What is Paper Battery … [Read more...]

Multiplexer is a electronic device which used to convert many to one. It transfers the multiple inputs to a single output line by selecting one of the inputs at a time with the help of selection lines. A 4:1 MUX has 4 inputs , 1 output and 2 selection lines. The verilog program for 4:1 MUX … [Read more...]
In a Asynchronous D Flip Flop, there is no direct synchronization between the clock and the ouput as the output will change at the instant when reset value changes. The output will not wait for the positive edge or negative edge of the clock pulse as in case of Synchronous D flip flop. The … [Read more...]
Synchronous D flip flop as its name suggests its output is synchronized with the positive edge or negative edge of the clock pulse. Verilog code for this flip flop along with the test bench is given below. Download the ouput at the end. /*Synchronous D flip flop Code by Anand Contact me at … [Read more...]
