Electron/Vacuum Tubes vs. Semiconductor Devices
Electronic circuitry has undergone tremendous changes since the advancement of a triode, a type of electron tube that consists of three elements namely filament, grid and plate. In a triode, the amount of current from the cathode to the plate (i.e. controlled current is a function of both the grid to cathode voltage (the controlling…

Insulated Gate Bipolar Transistor (IGBT) – Structure, Operation & Applications
IGBT is a voltage controlled device. It has high input impedance like a MOSFET and low on-state conduction losses like a BJT. In other words, this power device combines the voltage control of the MOSFET gate with the superior conduction characteristics of the bipolar device. Nonetheless, the IGBT utilizes injected-charge modulation in the base region…

Gunn Diode – Features, Operation & Applications
Features of a Gunn Diode A gunn diode is made up of only N-type semiconductor which is typically sandwiched between two metal conductors. The central section is usually lightly doped N– surrounded by heavily doped N+ layers. The central section is N-gallium arsenide whereas the two outer sections undergo epitaxial growth from GaAs with increased…

Types of Resistors
Resistors perform two basic functions in a circuit: they limit current flow and set voltage levels within a circuit. We have various kinds of resistors e.g. fixed resistors, variable resistors, digitally adjustable resistors, photoresistors, fusible resistors, etc. Generally, resistors can be broadly categorized as: Fixed Resistors Fixed resistors are those whose value cannot be changed…
