For any workplace, controlling potential electrical hazards is not always enough to ensure a safe working environment. Employees still have to follow some safety rules to prevent the risk of accidents resulting from electrical hazards. The same holds if you are working on electrical circuits or with electrical equipment and tools. One important note to … Read more
A differential amplifier is an op amp circuit which is designed to amplify the difference input available and reject the common-mode voltage. It is used for suppressing the effect of noise at the output. Since the noise present will be having the same amplitude at the two terminals of the op-amp. So when the difference … Read more
Slew rate is defined as the maximum rate of change of the op amp output voltage per unit of time in the closed-loop configuration under large-signal condition. Slew rate indicates how rapidly the op amp output can change in response to change in the input frequency. It is given as \[ \quicklatex{color=”#000000″ size=20} \boxed{Slew\; rate=\frac{\mathrm{d} … Read more
Peak Detector is a circuit which is used to detect the peaks of the applied input signal. It basically follows the input voltage and stores the peak voltage. It employs a diode and capacitor to implement this function. Types of Peak Detector Active peak detector Passive peak detector Active peak detector Active peak detectors use … Read more
Laplace transform is a mathematical tool that converts a function of a real variable to a function of a complex variable s (complex frequency). It is used for solving differential equations. Here is the Laplace transform table. Laplace transform table S.No. Function Laplace transform 1. 1 \[\frac{1}{s}\] 2. eat \[\frac{1}{s-a}\] 3. e−at \[\frac{1}{s+a}\] 4. tn … Read more
In an open-loop configuration, an ideal operational amplifier (op amp) behave as a comparator. The behaviour of op amp as a comparator is due to infinite open-loop gain. When it is working as a comparator, there are only two outputs possible at the output of op amp. Op amp as a Comparator Figure 1 shows … Read more
