Photo-diode is a two-terminal semiconductor P-N junction device and is designed to operate with reverse bias. The basic biasing arrangement, construction and symbols for the device are given in figure. It is either mounted in translucent case or has its semiconductor junction mounted beneath an optical lens. The output voltÂage is taken from across a
The photoconductive cell is a two terminal semiconductor device whose terminal resistance will vary (linearly) with the intensity of the inciÂdent light. For obvious reasons, it is frequently called a photoresistive device. The photoconductive materials most frequently used include cadmium sulphide (CdS) and cadmium selenide (CdSe). Both materials respond rather slowly to changes in light
Class D power amplifier. Class D power amplifier is a type of audio amplifier were the power handling devices are operated as binary switches. Since the power handling devices (MOSFETS) works as perfect binary switches, no time is wasted in between the transition of stages and no power is wasted in the zero input condition.
Class C power amplifier. Class C power amplifier is a type of amplifier where the active element (transistor) conduct for less than one half cycle of the input signal. Less than one half cycle means the conduction angle is less than 180° and its typical value is 80° to 120°. The reduced conduction angle improves
In class AB power amplifiers, the biasing circuit is so adjusted that the operating point Q lies near the cut-off voltage. During a small portion of negative half cycle and for complete positive half cycle of the signal, the input circuit remains forward biased–and hence collector current flows. But during a small portion (less
Harmonic distortion in power amplifiers. Distortion is a serious problem faced in power amplifier design. In faithful amplification the output signal must be a scaled replica of the input signal and if there is any dissimilarity between the input and output waveform, then the output is said to be distorted. Unpleasant sound output coming from
Class B power amplifier. Class B amplifier is a type of power amplifier where the active device (transistor) conducts only for one half cycle of the input signal. That means the conduction angle is 180° for a Class B amplifier. Since the active device is switched off for half the input cycle, the active device
TRANSFORMER-COUPLED CLASS A POWER AMPLIFIER This is also sometimes referred to as single ended power amplifier. The term “single ended” (denoting only one transistor) is used to distinguish it from the push-pull amplifier using two transistors. In case of a direct-coupled class A power amplifier shown, the quiescent current flows through the collector resistive load
Class A power amplifier. Class A power amplifier is a type of power amplifier where the output transistor is ON full time and the output current flows for the entire cycle of the input wave form. Class A power amplifier is the simplest of all power amplifier configurations. They have high fidelity and are totally
An optocoupler (or an optoelectronic coupler) is basically an interface between two circuits which operate at (usually) different voltage levels. The key advantage of an optocoupler is the electrical isolation between the input and output circuits. With an optocoupler, the only contact between the input and the output is a beam of light. Because of
What is an LCD/Definition of Liquid Crystal Displays The liquid-crystal display has the distinct advantage of having a low power consumption than the LED. It is typically of the order of microwatts for the display in comparison to the some order of milliwatts for LEDs. Low power consumption requirement has made it compatible with MOS
A Light Dependent Resistor (LDR) is also called a photoresistor or a cadmium sulfide (CdS) cell. It is also called a photoconductor. It is basically a photocell that works on the principle of photoconductivity. The passive component is basically a resistor whose resistance value decreases when the intensity of light decreases. This optoelectronic device is
Introduction Optoelectronics is the branch of electronics that combines optics and electronics. The devices that deal with this technology is called optoelectronics devices. Optoeletronic devices can be divided into two – light sensitive devices and light generating devices. We have already discussed a good amount of optoelectronic devices in our site. You can get the

You might have read about a “Diode” in many of your text books or electronics magazines/websites. But you still don’t get the concept? Don’t worry! In this article, we explain in detail about a semiconductor diode and its properties. Well, a diode is nothing but a PN junction. We have crafted two excellent articles about
What is a tunnel diode? Dr.Leo Esaki invented a tunnel diode, which is also known as “Esaki diode” on behalf of its inventor. Its a high conductivity two terminal P-N junction diode doped heavily about 1000 times greater than a conventional junction diode. Because of heavy doping depletion layer width is reduced to an extremely
Vacuum Diodes-Applications and Construction The simplest form of the electron tube for the production and control of free electrons is a Vacuum diode. Two electrodes are there for a vacuum diode known as anode and cathode. Cathode serves as an emitter of electrons where as anode serves as a collector of electrons. Cathode may be
An electronic galvanometer is a vacuum tube or transistor amplifier, followed by a milli ammeter may be employed as a detector. Some devices have arbitrary scale values, sometimes with variable gain and are designed simply as balance detectors. Sensitivity of such devices may be of the order of a microvolt per scale division or better,
