Power BJT - Construction, Operation and its Characteristics: Power transistors are large-area devices. Because of differences in geometry and doping concentrations, their properties tend to vary from those of the…
Shockley Diode Equation, Symbol, Operation and Applications: The four layer diode, also called the Shockley diode after its inÂventor Willian Shockley, is essentially a low-current SCR without a gate. It…
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…
Cascaded Differential Amplifier Working Principle: Cascaded Differential Amplifier Working Principle - Figure 20.53 gives an idea of how differential amplifiers can be cascaded to give an op-amp. Here the output…
Constant Current Bias in Differential Amplifier: In the differential amplifiers discussed so far, we have used the combination of RE and VEE to produce emitter dc bias current. Alternatively, constant…
Constant Current Source in Differential Amplifier: An ideal current source provides a constant current regardless of the load connected to it. There are many applications in electronics for a circuit…
Single Input Balanced Output Differential Amplifier: In a single input balanced output differential amplifier an input signal is applied to either input, with the other input connected to ground. However,…
Dual Input Unbalanced Output Differential Amplifier: It is an important configuration and converts dual inputs into a single ended output. In this configuration, two input signals are applied and the…
