STUDY OF OP-AMP



An operational amplifier or op-amp is a linear integrated circuit that has a very high voltage
gain, high input impedance and low output impedance. Op-amp is basically a differential amplifier
whose basic function is to amplify the difference between two input signals.
Op-amp has five basic terminals, that is, two input terminals, one o/p terminal and two
power supply terminals. Pin2 is called the inverting input terminal and it gives opposite polarity at
the output if a signal is applied to it ....etc

ABSTRACT
Nowadays, digital memories are used in each and every fields of day-to-day life. Semiconductors form the fundamental building blocks of the modern electronic world providing the brains and the memory of products all around us from washing machines to super computers. But now we are entering an era of material limited scaling. Continuous scaling has required the introduction of new materials.
Current memory technologies have a lot of limitations. The new memory technologies ....etc

Digital-to-Analog Analog-to-Digital
Data Handling Systems
Both data about the physical world and control signals sent to interact with the physical world are typically analog or continuously varying quantities.
In order to use the power of digital electronics, one must convert from analog to digital form on the experimental measurement end and convert from digital to analog form on the control or output end of a laboratory system.
Digital-to-Analog Conversion
When data is in binary form, the 0's and 1's may be of s ....etc

LASER TORCH BASED VOICE TRANSMITTER AND RECEIVER
Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit (Fig. 1) comprises c ....etc

OPERATIONAL AMPLIFIERS
OPERATIONAL AMPLIFIERS (OP-AMP)
The standard operational amplifier (op-amp) symbol is shown in Figure 12-1(a). It has two terminals, the inverting input
(-) and the non inverting input (+), and one output terminal. The typical op-amp operates with two dc supply voltages, one positive and the other negative, as shown in Figure 12-1(b). Usually these dc voltage terminals are left off the schematic symbol for simplicity but are always understood to be there.

CHARACTERISTICS OF OPERATIONAL AMPLIFIERS

Objective:

The objective of this experiment is to observe and measure several important operational amplifier characteristics. These characteristics are mostly a product of the bipolar transistor construction of the actual amplifier. They are especially attributable to the pair of differentially oriented transistors at the amplifier input. Two of the characteristics can be attributed to the internal compensation capacitor of the 741 Op amp. In this experiment, the ....etc

ABSTRACT

A pipelined analog-to-digital converter (ADC) architecture suitable for high-speed (150 MHz), Nyquist-rate A/D conversion is presented. At the input of the converter, two parallel track-and-hold circuits are used to separately drive the sub-ADC of a 2.8-b first pipeline stage and the input to two time-interleaved residue generation paths. Beyond the first pipeline stage, each residue path includes a cascade of two 1.5-b pipeline stages followed by a 4-b backend folding ADC. The full-scale residue range at the output of the pipeline ....etc

Understanding Operational Amplifier Specifications



Introduction

The term operational amplifier, abbreviated op amp, was coined in
the 1940s to refer to a special kind of amplifier that, by proper
selection of external components, can be configured to perform a
variety of mathematical operations. Early op amps were made
from vacuum tubes consuming lots of space and energy. Later op
amps were made smaller by implementing them with discrete
transistors. Today, op amps are mon ....etc

What is DAC? Digital to analog converter (DAC) is used to get analog voltage corresponding to an input digital data. Data in binary digital form can be converted to corresponding analog form by using a R-2R ladder (binary weighted resistor) network and a summing amplifier. It is more common and practical. Below is the circuit and output simulated waveform of R-2R ladder network DAC. This circuit also uses an op amp (741) summing amplifier circuit.
You can learn how to build a Digital to Analog converter using the simple technique explained in ....etc

ABSTRACT

The present seminar deals with the explanation of the advantages & necessity of solar power in the present world through solar powered vehicles. Solar-powered vehicles (SPVs), such as cars, boats, bicycles, and even airplanes, use solar energy to either power an electric motor directly, and/or use solar energy to charge a battery, which powers the motor. They use an array of solar photovoltaic (PV) cells (or modules made of cells) that convert sunlight into electricity. The electricity either goes directly to an electric m ....etc
