Both half adder and full adder comes under the category of combinational logic circuits that are used for arithmetic operations. However, there exist many differences between the two. The major difference between the half adder and the full adder is that the half adder operates on 2 inputs. On the contrary, full adder operates on …
Both diode and transistor are semiconductor devices and are the major part of electronic circuitry. However, there exist several differences between the two. The major difference between diode and transistor is that a diode is a 2 terminal device formed by merging p and n-type semiconductor material. As against, the transistor is a 3 terminal …
Half Wave and Full Wave Rectifiers are the two categories of rectifier circuits. The crucial difference between Half Wave and Full Wave Rectifier is that a half wave rectifier converts only one-half cycle of the ac input supplied into pulsating dc signal. As against a full wave, rectifier converts both halves of the applied input …

Definition: NPN transistor is a type of bipolar transistor that has 3 layers and is used for signal amplification. It is a current controlled device. NPN is an abbreviation used for a negative positive negative transistor. This means a p-type semiconductor is fused between 2 n-type semiconductor material. It has 3 regions namely emitter, base …
Definition: LED is a PN junction diode, that emits light when a certain potential is provided to the diode. LED is the short form for Light Emitting Diode and is a forward-biased device. This means it operates only when a forward voltage is applied to it. It is a semiconductor device whose operating principle is …
Definition: Varactor Diode is a PN junction diode that is especially operated in reverse biased mode. It is a device whose capacitance varies with the variation in the applied reverse bias potential. It is also known as varicap or voltcap. The word varicap is derived from the combination of word variable and capacitor. As these …
Definition: A PIN diode is an advancement of normal PN junction diode. It is a 3-layer device in which an intrinsic layer i.e., undoped semiconductor is sandwiched between P and N regions. Thus, making it a PIN diode. The presence of intrinsic region exhibits high resistance property. Due to this, the magnitude of the electric …
Definition: A heavily doped two-terminal semiconductor device through which electric current flows because of tunneling ( or tunnelling) of electrons is known as Tunnel Diode. It possesses the negative resistance characteristic in which current decreases even when the applied voltage is increased. Tunneling basically denotes the penetration of electrons through the depletion region. As highly …
Definition: A special type of PN junction diode that operates in reverse biased mode, more specifically in breakdown region is known as Zener Diode. The doping level of the zener diode is somewhat higher than the normal PN junction diode. So that it can give a sharp breakdown voltage. Zener breakdown was first noticed and …
Definition: An electronic component made of semiconductor material that allows conduction of current in only one direction is termed as a Diode. It is a two-terminal device normally formed by fusing p and n-type semiconductor materials each having majority and minority carriers. Let us first see the major contents of this article. Content: Diode Symbol …
