Delivering one of its latest innovations, Linear Technology, home of the Analog Gurus, has expanded its expertise in linear IC products to create the industry’s highest performancedigital-to-analog converter(DAC), the LTC2000.  End applications ranging from cable modems and other communications-based applications to test equipment and instrumentation will benefit from this leap in performance. The key to LTC2000’s leadership is in the generation of high frequency and broadbandsignals with a low noise floor and high spectral purity.  As shown in figure 1, the spectral purity, as measured by the spurious-free dynamic range (SFDR), exceeds the competition by over 10dB at almost every frequency point.

A device which controls the current flowing into the channel on application of low-power electrical signal is called a transistor. Roughly, transistors can be classified as Bipolar Junction Transistors (BJTs) and Field Effect Transistors (FETs). In BJTs, a small amount of current is used to control the current flowing into the channel and hence BJTs are also known as current controlled devices. In FETs, a small voltage is used to control the current flowing and hence called as voltage controlled devices. This article briefs about the various types of FETs with a comparison chart. Let’s get started.

Comparison of Personal Wireless Network Protocols

How cool it would be when devices on your workbench are interconnected? Creating a personal space for yourself where one of your devices acts as a server or a hub and allows you to access any information from any of your devices!! Sounds cool right? It would be super awesome when such connections are wireless. You can relish many facilities like Internet, GPRS, etc. All this has a technical term “Personal Area Network (PAN)”.

How to interface DAC 0832 IC based module with 8051 microcontroller?


Tularam M Bansod

Digital to analog conversion is very old technology. This conversion helps to create sound from digital media. This digital media can be MP3, MP4 songs. There are many applications of these conversions. What I noticed that in many our university curriculum, they prescribed that you have to use DAC0808 IC to do this conversion experiment.

I tried to do this experiment for our one client; I noticed that it requires ‘negative -12 voltage” power supply and cost of that power adapter is added in the experiments. Nowadays budget of polytechnic colleges is reducing day by day. I decided to read and do experiment with alternate DAC IC.

How to interface Temperature controller module in C and Assembly Language code?

This is simple experiment, where we have to connect temperature sensor module with 8051 microcontroller. Actual IC could be P8951RD2 also.  As temperature is physical quantity, it can be measured in analog only. We need some sensor which sense temperature. Then we have to process this value by Analog to Digital converter. We can use LM35 as temperature sensor. We will use one ADC0808 IC which will convert analog value of temperature in to digital for 8051  micro-controller.

The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. 

All About FINFET

A FinFET is classified as a type of multi-gate Metal Oxide Semiconductor Field Effect Transistor (MOSFET). It was first developed at the University of Berkley, California by Chenming Hu and his colleagues. A multi-gate transistor incorporates more than one gate in to one single device. In FinFET, a thin silicon film wrapped over the conducting channel forms the body. The name has been derived from the fact that the structure, when viewed, looks like a set of fins. The thickness of the device determines the channel length of the device.

In 2002, Cypress semiconductors started shipping a family of microcontrollers called Programmable system on chip. This family consists of a CPU core and configurable analog and digital blocks which makes it different from traditional microcontrollers. The traditional chips consist only of CPU cores whereas configurable blocks can be found in FPGA, CPLD and ASIC. A PSoC combines the architecture of both making it one of a kind.  A System on Chip is a single chip performing functions of several chips put together.

This article examines the calibration of sensor signal conditioning algorithms implemented in signal conditioners that transmit data in analog form. Note that sensor calibration includes the sense-element non-idealities as well as signal-conditioner non-idealities, such as offset and gain errors. The calibration scheme will take care of analog signal-chain errors of the analog circuit that are in front and back of the digital circuits.
