Which semiconductor acts as unipolar device

It has a low forward voltage drop and near-zero reverse recovery time hence used in very fast switching circuits. Schottky barrier diode can be used as a low noise amplifier due to metal-semiconductor junction. Get Started for Free Download App. Calculate the RMS value and average value, respectively, for the current over one cycle. Consider the following statements regarding rectifier circuits 1. Ripple factor for single-phase half-wave rectifier is 1.

Ripple factor single phase full wave rectifier is 0. Ripple factor for the three-phase half-wave rectifier is 0. A circuit using diodes and capacitors that increases input voltage by two, three or four times is. Which one of the following is a common application of a crystal diode? Zener diode works under which region of V - I characteristics of the semiconductor diode? Suggested Test Series. More Analog Electronics Questions Q1.

What is the typical value of open-loop voltage gain, AVOL, for a op-amp? The fixed bias circuit as shown is used as a collector bias circuit. What is the value of RB? UJT: It is 3-lead electronic semiconductor device with only 1 junction that acts exclusively as an electrically controlled switch.

A MOSFET is known as a voltage controlled device because a voltage applied to the gate controls the flow of current between the source and drain. For a BJT the principal is the same. It is a current controlled device because the base current controls the current flow from the emitter to collector. Skip to content Technology. April 30, Joe Ford.
