What is a Transducer?
Definition: The device which converts the one form of energy into another is known as the transducer. The process of conversion is known as transduction. The conversion is done by sensing and transducing the physical quantities like temperature, pressure, sound, etc. The electrical transducer converts the mechanical energy into an electric signal. The electrical signal may be voltage,…
Analog to Digital Converter
From the name itself it is clear that it is a converter which converts the analog (continuously variable) signal to digital signal. This is really an electronic integrated circuit which…
Digital to Analog Converters
A Digital to Analog Converter (DAC) converts a digital input signal into an analog output signal. The digital signal is represented with a binary code, which is a combination of bits 0…
Inverting & Non-Inverting Amplifier
Inverting amplifier In an inverting amplifier circuit, the operational amplifier inverting input receives feedback from the output of the amplifier. Assuming the op-amp is ideal and applying the concept of…
Operational Amplifier Basics
Operational Amplifiers, or Op-amps as they are more commonly ca Operational amplifiers are linear devices that have all the properties required for nearly ideal DC amplification and are therefore used extensively in signal…
Transistor Biasing
Biasing is the process of providing DC voltage which helps in the functioning of the circuit. A transistor is based in order to make the emitter base junction forward biased…
Field Effect Transistors
A Field Effect Transistor (FET) is a three-terminal semiconductor device. Its operation is based on a controlled input voltage. By appearance JFET and bipolar transistors are very similar. However, BJT…
Bipolar Junction Transistors (BJT)
The invention of the bipolar transistor in 1948 ushered in a revolution in electronics. Technical feats previously requiring relatively large, mechanically fragile, power-hungry vacuum tubes were suddenly achievable with tiny,…
Forward Bias and Reverse Bias
A forward-biased diode conducts current and drops a small voltage across it, leaving most of the battery voltage dropped across the lamp. If the battery’s polarity is reversed, the diode…
P-N junction semiconductor diode
What is p-n junction semiconductor diode? A p-n junction diode is two-terminal or two-electrode semiconductor device, which allows the electric current in only one direction while blocks the electric current in opposite…
