Class A Power Amplifiers (Direct Coupled with Resistive Load): A class A power amplifiers is defined as a power amplifier in which output current flows for the entire cycle (360°)…
What is Comparator in Electronics? - Classification and Applications A circuit used to mark the instant when an arbitrary waveform attains some particular reference level is called a comparator. The…
PN Diode Switching Times: A P-N junction diode may be used as an electrical switch. The electrical circuit can be made 'on' and 'off' by forward biasing or reverse biasing…
Zero bias PN junction: Zero bias PN junction - Here we will examine the properties of the step junction in thermal equilibrium, where no currents exist and no external excitation…
Basic Structure of PN Junction in Semiconductor: Most semiconductor devices employ one or more P-N junctions. The P-N junction is the control element for the performance of all semiconductor devices…
What is Hall Effect in Semiconductor?: When a specimen (metal or semiconductor) is placed in a transverse magnetic field and a direct current is passed through it, then an electric…
Relaxation Time, Collision Time and Mean Free Path: The relaxation time is closely related to the mean time of flight between collision and also to the mean free path of…
What is Intrinsic Semiconductor? An intrinsic semiconductor is one which is made of the semiconductor material in its extremely pure form. A semiconductor is not truly intrinsic unless its impurity…
