What Are Flexible PCBs and Why Use Them?
Rigid PCBs that serve the purpose of making electronic devices operational are not compatible with high-tech advanced gadgets. As engineers are required to provide PCB solutions that match complex designs, shapes, and product specifications, flexible PCBs have better advantages for building a new era of products. The space and power demands of new-age products are…

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…
