The Operational Amplifier or Op-Amp is a high performance linear amplifier with an amazing variety os amplification The Op-Amp has two inputs, inverting (-) and non-inverting (+), and one output. The polarity of a signal applied to the inverting input is reversed at the output. A signal...

We have seen that, the output of integrator is a Triangular Wave Generator Using Op amp if its input is a square wave. This means that a Triangular Wave Generator Using Op amp can be formed by simply connecting an integrator to the square wave generator as shown in the Fig. 2.85. Basica...

Op-amp Basics (part 1): Operational amplifiers (op-amps) are some of the most important, widely used, and versatile circuits in use today. The first op-amp used vacuum tubes and was released in 1941 by Bell Labs. The ubiquitous ua741 was released in 1968
Fig. 21 above depicts a functional square wave generator circuit centered around an op amp. This square wave generator circuit could possibly be the most straightforward one. Just three external resistors and one capacitor are needed in addition to the op amp itself. ...
Use the first waveform generator as source VIN to provide a 2 V amplitude, 1 kHz sine wave excitation to the circuit. The second waveform generator is used to generate 1 V constant voltage. Configure the scope so that the input signal is displayed on Channel 2 and the output signal is di...
sine wave out. As with the previous blog the circuit came from a book, though I've taken it and adapted it for 5V single-supply operation using just the very cheapest-of-cheap quad op-amps. This one has an interesting feature in that it produces two sine waves rather than one. ...
Deletion of C2 removes the averaging function and provides a precision full-wave rectifier, and deletion of C1 provides an absolute value generator. Circuit operation may be understood by following the signal path for negative and then for positive inputs. For negative signals, the output of ...
