Voltage Level Translator (Level Shifter): Voltage Level Translator (Level Shifter) is usually an emitter follower circuit which is used to shift the dc level at the output of the intermediate…
Emitter Follower at High Frequencies: Emitter Follower at High Frequencies circuit is given in Fig. 19.48(a). A capacitance CL is included across the load because the emitter follower is often…
Voltage Amplifier - Definition and Equivalent Circuit: Voltage amplifiers are intended to amplify an input voltage signal and provide an output voltage signal. The voltage amplifiers is essentially a voltage-controlled…
Difference between Voltage Amplifier and Power Amplifier: The Difference between Voltage Amplifier and Power Amplifier are discussed below The primary function of the voltage amplifier is to raise the voltage…
FET as a Voltage Variable Resistor (VVR): FET is a device that is usually operated in the constant-current portion of its output characteristics. But if it is operated in the…
LM340 Series Voltage Regulator: This LM340 Series Voltage Regulator is typical of the three-terminal voltage regulators. The block diagram is shown in Fig. 43.27. The built-in reference voltage Vref drives…
Fixed Positive Voltage Regulators: The series 7800 regulators provide eight voltage options, rangÂing from 5 to 24 V, as indicated in Table 43.2. These ICs are designed as fixed voltage…
IC Voltage Regulators: IC voltage regulators are versatile and relatively inexpensive and are available with features such as a programmable output, current-voltage boosting, internal short-circuit current limiting, thermal shutdown, and…
