Light Activated SCR (LASCR) - Symbol, Construction and Operation: Light activated SCR is just an ordinary SCR except that it can also be light triggered. Most LASCRs also have a…
n Stage Cascaded Amplifier: As already discussed, several amplifier stages are usually cascaded to increase the overall voltage gain of the amplifier. However, sometimes cascading is done to obtain the…
Enhancement Type MOSFET - Construction, Operation and Characteristics: Although DE-MOSFET is useful in special applications, it does not enjoy widespread use. However, it played an important role in history because…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are…
Diode Clipping Circuit - Types and Applications: Diode Clipping Circuit - For a clipping circuit at least two components—an ideal diode and resistor are required and sometimes a dc battery…
What is Transistor Transistor Logic (TTL) Circuit? Texas instruments introduced transistor transistor logic (TTL), a widely used family of digital devices in 1964. It is fast, inexpensive and easy to…
Three Phase Rectifiers: Three-Phase Half-Wave Rectifier : Figure 9.11 illustrates a circuit for a 3-phase half-wave rectifier. The three diodes are connected to the three phases of a 3-phase transformer…
Voltage Multipliers - Voltage Doublers, Triplers and Quadruplers Voltage multipliers is a modified capacitor filter circuit that delivers a dc voltage twice or more times of the peak value (amplitude)…
