Op Amp Voltage Regulators: Voltage Follower Regulator - Refer once again to the Op Amp Voltage Regulators circuit in Fig. 17-11. The complete error amplifier has two input terminals at…
Voltage Series Negative Feedback Amplifier: In a negative feedback amplifier, a small portion of the output voltage is fed back to the input. When the feedback voltage is applied in…
Amplifier Testing: Preparation - Transistor Amplifier Testing and other circuits should be tested in a methodical fashion; otherwise the results obtained may be useless. The circuit should first be carefully…
Capacitor Coupled Common Base Amplifier: A practical Capacitor Coupled Common Base Amplifier (using a plus/minus supply) is shown in Fig. 12-39. [Note the polarity of the input coupling capacitor (C1).]…
Heat Sink in Transistor: When power is dissipated in a transistor, the heat generated must flow from the collector-base junction to the case, and then to the surrounding atmosphere. When…
High Frequency Analysis of BJT: Coupling and Bypass Capacitor Effects - Consider the typical High Frequency Analysis of BJT illustrated in Fig. 8-5. As discussed, the amplifier voltage gain is…
Transistor Models and Parameters: T-Equivalent Circuit - Because a transistor consists of two pn-junctions with a common centre block, it should be possible to use two pn-junction ac equivalent circuits…
Submarine Cables: Submarine cables use principles very much like those of coaxial cables. Thus they are coaxial, have repeaters and equalizers and have dc power fed to them, with opposite…
