The switching is required in many applications at low as well as at high frequency. RF MEMS switches are the specific micromechanical switches that are designed to operate at RF to mmWave frequencies. MEMS switches usages some mechanical movement to achieve a closed or open circuit in the Radio...
Find bellow an Android TCP client extension
that implements a very simple socket; note that its operation is performed 'one-shot', which means that only one command is sent ( and its respective response, read ) at a time, and then the socket connection is closed. So, be aware that it is not a...
Generating Sine wave is very demanded job in power electronics field. So do to me too. I read some topics over the internet and found many ways to generate a sine wave. As most of you are really interested in generating sine wave so I’m writing today about it here.
There is some different ways...
The following attached file contains an SSH Client extension
which I made for my own use, but it may also be useful for users of the MIT Application Inventor 2 (AI2) community, or even to the AppyBuilder community (code intrinsically compatible for the last one, but not tested). This is just the...
The Emergence of Power Integrity Analysis
As the speed of the data signal increases, many reasons including power supply noise lead to the degradation of the high-speed signals. In low power high-speed digital interfaces, it is crucial to characterize the whole system power supply in order to...

The journal from ITRS(International Technology Roadmap for semiconductor) is available for free downloading.The available journal is of the last year...and it...
Polar modulation is analogous to IQ modulation in the same way that polar coordinates are analogous to Cartesian coordinates.
For Quadrature modulator approach to digital radio transmission requires a linear RF power amplifier, which creates a design conflict between improving power...
Hi all. serial communication is widely used nowadays. For ex: Controlling a DC motor , stepper motor, or anything from your PC. First thing you get in your mind is serial communication. While encountering serial communication. First thing you get after searching is RS232 and then MAX232. So i...
Hi,
Purpose of the Heart Risk Warner project is to assess your heart risk. But also, you can measure blood pressure, heart rate, temperature, ecg and ppg waves, or get your activity and body movements. With Bluetooth you can transfer data or store it into microSD card.
I think it could be...
Hi everyone,
I invite you all to take a peek at my first installment of my new "Low Noise Amplifier Design Series" Blog.

few month past i came to know with my observation that embedded linux demands in market going high and i must have to upgrade myself from 8/16 bit processors to 32/64 bit. but i did not understand why and how i had to upgrade. i have posted in different forum for help but the unfortunately the...
Are you ready for SystemVerilog 2012? Two features I think you will find very useful for functional verification: https://go.mentor.com/ready-for-systemverilog-2012
Our Event Electro Fiesta’ 2013
CDS is celebrating 21 years of service to the IT industry. Thus this year we are organizing an Electro Fiesta’ 2013, A National Level Electronics Project Design Competition & Open Electronic Quiz Competition, at Birla Industrial & Technological Museum (BITM)...
As an electronics engineer, I find a very limited number of electronic circuit simulators available in the market. SPICE is the industry standard language for circuit simulations, but for circuits with limited complexities. If the design consists of programmable devices like microcontrollers...

well.. she is turning 22 and i didnt had a chance to get her anything for past 10 year or so :-(. so i wanted this to be a special gift for her. Thought of buying some form local gift shops but i wanted it to be personal.
So I made her an electronic magic 8 ball.
so here goes.

Here I will show you how to use the compare section of the CCP (Compare, Capture, Pulse Width Modulation) module of the PIC16F877A. You can use this concept for any PIC with a CCP/ECCP module.
There are 2 modules associated with the compare section – the CCP module which we’ll use for the...
Dear friends,

I turned the switch on and BOOM! That noise, the tiny puff of smoke and the accompanying smell had become far too familiar.
I looked on in confusion at all the failed electronics components in front of me. I needed answers. Why did the H-bridge circuit not work as “claimed”? Books showed...
Lots of PIC projects involve the use of LCD screens as user interface. But these LCDs won't work just by connecting some wires from PIC to LCD. In fact you actually need to use proper commands to tell the LCD what to do. And here I come in help for you!
I've seen lots of LCD drivers out there...
In most cases where you want to control an AC load, a triac or SCRs will be used. However, it is not easy to drive a triac or SCR. The drive requirement for the triac or SCR makes it sometimes difficult to control it as we want. One thing is that we can not turn the triac or SCR on or off as we...
My desire to make solar projection and observe the transit of Venus, made me to buy a telescope. I cam to my home town Kakinada form Hyderabad.
Actually at my region the transit of Venus starts almost one hour before sun rise and it was in progress during sun rise. we can not observe the...
We all know what a motor is and what it does. The simplest way to run a motor is to just connect it to a power source. For a DC motor, that would mean, just connecting the motor to the DC voltage that the motor was rated for (or less). But, can you control the speed?
Yes. The simplest method...
Here's a temperature sensor (thermometer) circuit that you can easily build. It uses the popular PIC 16F877A microcontroller. The temperature sensor is DS18S20. The DS18S20 communicates through the one-wire protocol. The PIC16F877A communicates with the DS18S20 with the one-wire protocol and...
Here's one temperature sensor (thermometer) circuit that you can easily build. It uses the popular PIC 16F877A microcontroller. The temperature sensor is LM35. The LM35 outputs an analog voltage proportional to the temperature. The output from the LM35 is 0.1V/'C. So, when temperature sensed is...
Zero crossing detection is very important, especially in power control circuits employing thyristors.
