What are the Linear Applications of Opamp? Explain with Diagrams & Derivations
The linear applications of Opamp are discussed in this topic with neat circuit diagrams and mathematical derivations. These applications are: inverting amplifier, non-inverting amplifier, adder, subtractor, buffer, integrator and differentiator.
What is Operational Amplifier? Explain its Characteristics & Parameters
An opamp is defined as the high gain direct coupled amplifier, which consists of one or more differential amplifiers with other supporting circuits. The operational amplifier can perform mathematical operations like addition, subtraction, integration, differentiation and comparison.
What is the need for Dual Power Supply in Differential Amplifier? Compare working with Single & Dual Power Supply
The differential amplifier works good, on dual power supply only. However, if it is connected with single power supply, then it’s working becomes unstable. So its comparative points of its working for dual and single power supply are given below.
What is Differential Amplifier? Explain in details
The Differential Amplifier is the super quality amplifier used in operational amplifiers. As its name implies, it amplifies the difference of two input signals i.e. V1 and V2 and gives the output. Hence it is called as differential amplifier.
Fundamentals of Operational Amplifier
An operational amplifier (Opamp) is a versatile device which can be used to amplify AC as well as DC signals. It is manufactured in the form of integrated circuit package. It can perform different mathematical operations like addition, subtraction, integration, taking the derivative, comparison, etc. Hence it is known as operational amplifier.
How Piezo Electric Crystal works? What are the different axes of crystal?
The Piezo Electric Crystal is used to measure pressure. Piezo is an Italian word meaning pressure. It is very accurate in measurement. A piezo crystal is a transducer which can convert pressure into electrical signal. It is an active transducer. It is found that Rochelle salt and Tourmaline substances.
How Linear Variable Differential Transformer works? Explain its three cases
The Linear Variable Differential Transformer is a passive transducer. It measures force in terms of displacement of ferromagnetic core of a transformer. It is based on the principle of magnetic induction.
How capacitive transducer works? Explain with diagram
Capacitive transducer is also known as pressure transducer. It is a passive transducer. It is used to measure external pressure and displacement also. It works on the principle of parallel plate capacitor.
What is Light Dependent Resistor (LDR)? Explain with diagram
The Light Dependent Resistor means an LDR. It is a passive transducer. It is also known as photoconductive cell because its conductivity changes due to change in light intensity.
What is thermistor? How it is used in Wheatstone Bridge?
What is thermistor: It is a passive temperature transducer so battery must be used in its circuit. Thus a thermistor is a transducer which changes its resistance due to change in temperature.
What is transducer? What are the selection criteria of transducer?
Before discussing about what is transducer, first we shall see basic difference between sensor and a transducer. They both are used to sense a change within the environment they are surrounded by or an object they are attached to. However, a sensor will give an output in the same format and a transducer will convert the measurement into an electrical signal.
