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 Two Stage CE Amplifier: A Capacitor Coupled Two Stage CE Amplifier circuit is shown in Fig. 12- 15 . Stage-1 is capacitor-coupled (via C3) to the input of…
Decibels and Half Power Point Method: Power Measurement in Decibels and Half Power Point Method - The power gain (Ap) of an amplifier may be expressed in terms of the…
Common Emitter Amplifier Circuit: Consider the Common Emitter Amplifier Circuit circuit shown in Fig. 6-17. When the capacitors are regarded as ac short-circuits, it is seen that the circuit input…
Cryogenically Cooled Amplifiers: The term solid-state is used deliberately here; it does not mean "semiconductor." In terms of the somewhat older maser parlance, it means the opposite of gaseous, i.e.,…
Negative Resistance Amplifier: The classical application of the tunnel diode was in microwave oscillators, especially after it was realized that the secret of stable oscillations lay in loosely coupling the…
Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
Parametric Amplifier: The parametric amplifier uses a device whose reactance is varied in such a manner that amplification results. It is low-noise because no resistance need be involved in the…
