Circuit Analysis Circuit Analysis Developing an understanding of circuits is the first step in learning about the modern-day electronic devices that dominate what is becoming known as the "Information Age. More simply, this is another way of looking at the law of conservation of charge.
Just type and press 'enter' Search for: In addition to basic op amp circuits like the Differential amplifier, Inverting and Non-inverting amplifiers, Summing amplifier etc.
We have classified this list into three parts: To learn about it click on the link — Operational Amplifiers Op-amps The above linked article contains all the basics of op-amps, with the basic op-amp circuit with two transistors.
The different advantages of op-amps are also specified, along with links to different basic op-amp circuits like Comparator Circuit, Schmitt Trigger Circuit, Astable Multivibrator, Monostable Multivibrator, Zero-crossing detector, voltage splitter and so on.
The article also contains information about the IC, its packaging style, the use of op-amp as an inverting and non-inverting circuit, and so on.
The different pin assignments of the IC are also explained with neat figures. Given below are some links to some of the best op-amp based circuits designed by us.
Most of them are simple and easy to make a home. We have given a very detailed description and circuit diagram for every one of the. The main use of the LDR is to sense the presence of a person through his shadow falling on the sensor.
As soon as the shadow falls on it, the resistance of the device begins to increase. A timer IC is also used to be triggered by a transistor and thus to drive the alarm load. Read more about the working of the circuit from the link above.
Transistor Amplifier Circuit Watts This circuit is very simple and inexpensive. Only one uA op-amp and four transistors are required for the working of this circuit.
The op-amp produces the gain required and the transistors are connected to work as the speaker driver. The circuit is highly stable and is also known to produce a reasonable output of 12 Watts on a 4 Ohm speaker. The op-amp used here is the IC LM Two op-amps from the chip are selected and are used to amplify the sound picked by the condenser microphone.
The third op-amp inside the IC is used as a level detector. The op-amp is connected as a non-inverting amplifier, and can be easily setup as a sound level checker at homes and theatres.
You will find it very useful in checking the sound pressure of each channel on different positions of the room. Infrared Motion Detector Circuit This circuit is used to produce an alarm as soon as an intruder walks across the infrared rays produced by an IR diode.
A timer IC is also used here to work as an astable multivibrator. The beams produced by the IR diode are received by a photo-transistor. When an intruder walks by, the LM op-amp senses the difference in phase and automatically goes high. Passive Tone Control Circuit The circuit uses op-amp as the only active element, whereas all the other components are passive elements.
Thus, the circuit got its name as Passive Tone Control Circuit. The circuit is divided into two parts — the op-amp based pre-amplifier and the Baxandall tone control circuitry. The op-amp used here is the TL IC.
The Baxandall circuit principles and the whole circuit is explained in detail in the original article. This circuit does have some disadvantages like energy wastage, and high distortion. Active Crossover Circuit This circuit can be considered just the opposite of the passive tone control circuit.
All the drawbacks that the passive circuit has is rectified by this circuit. They are known to be more suitable for HiFi audio systems. The circuit divides the complex audio signal into two bands, one being the low frequency signal, and the other being the low frequency signal.
These two signals are further amplified separately and is bi-amped to its corresponding low frequency and high frequency bands.
The op-amp used here is the LM IC, which is basically a dual op-amp that is designed for audio purposes.Design of Integrated Circuits for Optical Communications [Behzad Razavi] on rutadeltambor.com *FREE* shipping on qualifying offers.

What is the use of voltage stabilizer? Voltage stabilizers are used to stabilize the input voltage to protect the rest of circuitry from unwanted electrical spikes, nowadays some devices have inbuilt stabilizer circuit.

Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens when elements are connected together into a circuit. Video created by Georgia Institute of Technology for the course "Linear Circuits 2: AC Analysis ". This module describes how to analyze circuits with sinusoidal inputs Learn online and earn valuable credentials from top universities like Yale.
Network analysis is the process of finding the voltages across, and the currents through, every component in the network.
There are many different techniques for calculating these values. However, for the most part, the applied technique assumes that the components of the network are all linear.
Simplifying complex circuits can make your analysis easier (plus you can try different loads to meet circuit requirements). But if you mess up the simplification, you inevitably lose terminals, resulting in a circuit that isn’t equivalent.
