What is Clipper Circuit? - Definition and Classification Clipper Circuit is one which controls the shape of the waveform by removing or "clipping" off an unwanted portion. A half-wave rectifier…
Switch Mode Power Supply (SMPS) or Switching Regulators: Switch Mode Power Supply (SMPS) - The regulated power supplies described earlier were basically linear voltage regulators. A linear voltage regulator possesses…
What is Dual Power Supply? -Circuit Diagram and its Workings? Many discrete and ICs need bipolar (dual power supply or ± V) supplies. This can be easily accomplished with two…
Shunt Voltage Regulator Block Diagram: A shunt voltage regulator provides regulation by shunting current away from the load. The block diagram of such a voltage regulator is depicted in Fig.…
Transistor Series Voltage Regulator or Emitter Follower Voltage Regulator: A simple series voltage regulator using an NPN transistor and a zener diode is shown in Fig. 43.5. This circuit is…
What is a Digital Integrated Circuit? In an integrated circuit, components such as diodes, transistors, resistors, inductors etc. are integral parts of the chip. And on surface of this chip,…
Leakage Current in a Transistor and Breakdown Voltage: Leakage Currents: In CB circuits shown in Fig. 10.77, if emitter current is made zero, the B-C junction still remains reverse biased…
Early Effect and Base Width Modulation: In active region, the emitter-base (EB) junction is forward biased and collector-base (CB) junction is reverse biased, so the barrier width at EB junction…
