Definition: Magneto resistors are those components that exhibit the property of magnetoresistance. Basically, magnetoresistance is the phenomenon of change in resistance of a material when a magnetic field is applied. The current that flows through a magneto resistor, varies with the variation in the applied magnetic field. The resistivity of magnetoresistor depends on the mobility …
Both resistor and capacitor are passive components that are employed in electrical and electronic circuits. However, the crucial difference between the resistor and the capacitor is that a resistor is an element that dissipates electric charge or energy. As against, a capacitor is an element that stores electric charge or energy. Basically, a resistor is …
Both transistor and thyristor are the types of semiconductor devices. But some factors exist that differentiates the two. The crucial difference between transistor and thyristor is that a transistor is a 3-layer device that requires regular current pulse in order to ensure conduction. On the contrary, a thyristor is a 4-layer device that needs an …
Definition: A Gunn diode is a semiconductor device formed by only N-type material. It is also termed as a transferred electron device. As in n-type material, electrons acts as majority carriers and these are transferred from one valley to another. It is a two terminal device basically made up of semiconductor material like GaAs, InP …
Definition: A signal generator is an equipment that is used to produce signals of varying amplitude and frequency. It is usually a source for generating sinusoidal signals. However, it can also produce a signal in the form of a square wave, triangular wave or sawtooth wave etc. The adjustable frequency range of the generated signal …
Definition: An oscillator is basically a signal generator that produces a sinusoidal or non-sinusoidal signal of some particular frequency. Oscillators find their various applications as these are the fundamental component of any electrical and electronic circuits. Continuous oscillations are the basis of working of an oscillator. Sometimes, an oscillator is said to be an amplifier …
Both intrinsic and extrinsic semiconductor is the 2 categorizations of semiconductor material. The difference between intrinsic and extrinsic semiconductor is that Intrinsic semiconductors are the pure form of semiconductor materials. Whereas extrinsic semiconductors are impure semiconductor formed by adding an impurity to a pure semiconductor. No, any external impurity is doped in case of an …

Definition: A Schottky diode is a 2 terminal metal-semiconductor device that is formed by diffusing an n-type semiconductor over a metal. Both metal and n-type semiconductor have electrons as their majority carriers, as almost negligible holes are present in a metal. As in Schottky diode, only majority charge carrier i.e., electrons are responsible for conduction. …
Definition: LCD is an acronym used for Liquid Crystal Display. It is basically a display technique in which liquid crystals are used in order to produce an image on the screen. Unlike an LED, an LCD does not hold the property of producing light. However, it allows some regions to appear either bright or dark …
Definition: JFET is the shortened form for Junction Field Effect Transistor. It is a 3 terminal semiconductor device in which current conduction takes place only due to the flow of majority charge carriers. Thus, it is a unipolar transistor. The 3 terminals of the JFET are source, drain and gate. Unlike BJT, JFET is a …
