Notes Low frequency signal mode of FET The low frequency signal mode of a field-effect transistor (FET) refers to the behavior of the transistor when it is operating in its linear region, where the output voltage is ...
Notes Series Regulations A functional block schematic of the series type regulator is shown in Figure. Vo is the regulation output voltage, whereas Vin is an unregulated dc output. The control element moves ...
Notes Barkhausen condition Consider an amplifier with gain A and a feedback route having gain β with gain (amount of output feedback to input). Then for this system to oscillate the loop gain ...
Notes Zener diode as voltage regulator When operating in the breakdown area, a zener diode can be utilized as a voltage regulator since it keeps the output voltage constant even when the current flowing through it ...
Notes Principle of switching regulator A switching regulator creates a pulse train using a pulse width modulator. The above image depicts the fundamental circuit. When the drive pulse is strong, Q1 is saturated and receives ...
